Syntax display mpls summary Views Any view Predefined user roles network-admin network-operator Examples # Display MPLS summary information. display mpls summary MPLS LSR ID : 2.2.2.
ftn enable Use ftn enable to enable the device to maintain FEC-to-NHLFE map (FTN) entries in the RIB. Use undo ftn enable to restore the default. Syntax ftn enable undo ftn enable Default The device does not maintain FTN entries in the RIB. Views RIB IPv4 address family view Predefined user roles network-admin Usage guidelines FTN entries are FIB entries that contain outgoing labels. When an LSR receives an unlabeled packet, it searches the corresponding FTN entry based on the destination IP address.
Views RIB IPv4 address family view Predefined user roles network-admin Parameter prefix-list-name: Specifies an IPv4 address prefix list, a case-sensitive string of 1 to 63 characters. This command applies to only the destination networks that permitted by the prefix list. Usage guidelines FTN forwarding adds a label to an unlabeled packet, and forwards the labeled packet. FTN forwarding statistics collection is enabled by this command.
Usage guidelines Execute this command on all interfaces that need to perform MPLS forwarding. Examples # Enable MPLS on interface GigabitEthernet 2/0/1. System-view [Sysname] interface gigabitethernet 2/0/1 [Sysname-GigabitEthernet2/0/1] mpls enable Related commands display mpls interface mpls label advertise Use mpls label advertise to specify the type of label the egress will advertise to the penultimate hop. Use undo mpls label advertise to restore the default.
Examples # Configure the egress device to advertise an explicit null label to the penultimate hop. system-view [Sysname] mpls label advertise explicit-null Related commands reset mpls ldp mpls lsr-id Use mpls lsr-id to configure an LSR ID for the local LSR. Use undo mpls lsr-id to delete the LSR ID of the local LSR. Syntax mpls lsr-id lsr-id undo mpls lsr-id Default An LSR has no LSR ID.
Default The MPLS MTU of an interface is not configured. Fragmentation for MPLS packets is based on the MTU of the interface, and the length of a fragment does not include that of the MPLS label. Thus, after an MPLS label is added into a fragment, the length of the MPLS fragment might exceed the interface MTU. Views Interface view Predefined user roles network-admin Parameters value: Specifies the MPLS MTU of the interface, in the range of 46 to 65535 bytes.
vpn-instance vpn-instance-name: Specifies a VPN instance by its name, a string of 1 to 31 case-sensitive characters. If you do not specify a VPN instance, the command enables MPLS forwarding statistics for the public-network LSPs. ipv4 ipv4-destination mask-length: Specifies the IPv4 LSP for an FEC specified by an IPv4 address and a mask length. The mask length is in the range of 0 to 32.
Syntax mpls statistics interval interval undo mpls statistics interval Default MPLS forwarding statistics reading is disabled. Views System view Predefined user roles network-admin Parameters interval: Specifies the MPLS label forwarding statistics reading interval in the range of 30 to 65535 seconds. Usage guidelines To display MPLS label forwarding statistics by using the display mpls lsp verbose command, you must perform the following tasks: 1.
Usage guidelines The mpls ttl expiration enable command enables an LSR to generate an ICMP TTL-expired message upon receiving an MPLS packet with TTL being 1. • If the MPLS packet has only one label, the LSR sends the ICMP TTL-expired message back to the source through IP routing. • If the MPLS packet has multiple labels, the LSR forwards the ICMP TTL-expired message along the LSP of the MPLS packet to the egress, which then sends the message back to the source.
Within an MPLS network, TTL is always copied between the labels of an MPLS packet. The mpls ttl propagate command affects only the propagation between IP TTL and label TTL. HP recommends setting the same TTL processing mode on all LSRs of an LSP. To enable TTL propagation for a VPN, you must enable it on all PE devices in the VPN. This allows you to obtain the same traceroute result (hop count) from those PEs. Examples # Enable TTL propagation for VPN packets.
Predefined user roles network-admin Parameters all: Specifies all LSPs. vpn-instance vpn-instance-name: Specifies a VPN instance by its name, a string of 1 to 31 case-sensitive characters. If you do not specify a VPN instance, the command clears MPLS forwarding statistics for the public-network LSPs. ipv4 ipv4-destination mask-length: Specifies the IPv4 LSP for an FEC specified by an IPv4 address and a mask length. The mask length is in the range of 0 to 32.

Syntax display mpls static-lsp [ lsp-name lsp-name ] Views Any view Predefined user roles network-admin network-operator Parameters lsp-name lsp-name: Specifies a static LSP by its name, a case-sensitive string of 1 to 15 characters. If you do not specify a static LSP, the command displays information about all static LSPs. Examples # Display information about all static LSPs.
static-lsp egress Use static-lsp egress to configure the egress node of a static LSP. Use undo static-lsp egress to delete the egress node configuration for a static LSP. Syntax static-lsp egress lsp-name in-label in-label undo static-lsp egress lsp-name Default No static LSP exists on the device. Views System view Predefined user roles network-admin Parameters lsp-name: Specifies a name for the static LSP, a case-sensitive string of 1 to 15 characters.

Syntax dscp dscp-value undo dscp Default The DSCP value for outgoing LDP packets is 48. Views LDP view Predefined user roles network-admin Parameters dscp-value: Specifies the DSCP value for outgoing LDP packets, in the range of 0 to 63. Usage guidelines To control the transmission preference of outgoing LDP packets, specify a DSCP value for outgoing LDP packets. Examples # Set the DSCP value for outgoing LDP packets to 56.
The graceful-restart command does not take effect on LDP sessions established before the command is executed. To apply the new setting, execute the reset mpls ldp command to reestablish LDP sessions. Examples # Enable GR for LDP. system-view [Sysname] mpls ldp [Sysname-ldp] graceful-restart Related commands • display mpls ldp parameter • reset mpls ldp graceful-restart timer Use graceful-restart timer to configure the MPLS Forwarding State Holding timer and the Reconnect timer for GR.
{ { If the LDP session is not set up before the Reconnect timer expires, the GR helper deletes stale FEC-label mappings and corresponding MPLS forwarding entries. If the LDP session is successfully set up before the Reconnect timer expires, the GR restarter sends the remaining time of the MPLS Forwarding State Holding timer to the GR helper. The remaining time is sent as the LDP Recovery time. 3. After the LDP session is reestablished, the GR helper starts the LDP Recovery timer. 4.
Usage guidelines LDP convergence on a link is completed when the following events occur: • The local device establishes an LDP session to at least one peer, and the LDP session is already in Operational state. • The local device has distributed the label mappings to at least one peer. If LDP notifies IGP immediately after convergence, MPLS traffic forwarding might be interrupted in one of the following scenarios: • LDP peers use the Ordered label distribution control mode.
Usage guidelines When an LDP restart or an active/standby switchover occurs, LDP takes time to converge, and LDP notifies IGP of the LDP-IGP synchronization status as follows. • If a notification delay is not configured, LDP immediately notifies IGP of the current synchronization states during convergence, and then updates the states after LDP convergence. This could impact IGP processing.
to operate correctly, you can enable LDP to redistribute BGP IPv4 unicast routes on the PE and the CE. The configuration enables LDP to assign labels to the BGP routes to establish LSPs. For more information about carrier's carrier, see MPLS Configuration Guide. Examples # Enable LDP to redistribute BGP IPv4 unicast routes on the public network.
Related commands display mpls ldp parameter loop-detect Use loop-detect to enable loop detection. Use undo loop-detect to disable loop detection. Syntax loop-detect undo loop-detect Default Loop detection is disabled. Views LDP view, LDP-VPN instance view Predefined user roles network-admin Usage guidelines This command enables LDP to detect and terminate LSP loops. LDP loop detection uses one of the following methods: • Hop count. For more information, see "maxhops." • Path vector.
Default LDP only uses redistributed host routes with a 32-bit mask to generate LSPs. Views LDP view, LDP-VPN instance view Predefined user roles network-admin Parameters all: Enables LDP to use all redistributed routes to generate LSPs. prefix-list prefix-name: Specifies an IP prefix list by its name, a case-sensitive string of 1 to 63 characters. LDP uses only the redistributed routes permitted by the IP prefix list to generate LSPs.
Default No LDP LSR ID is configured. LDP uses the MPLS LSR ID configured by the mpls lsr-id command for both the public network and VPN instances. Views LDP view, LDP-VPN instance view Predefined user roles network-admin Parameters lsr-id: Specifies an LDP LSR ID, in dotted decimal notation. Usage guidelines If you configure an LDP LSR ID by using the lsr-id command in LDP view or LDP-VPN instance view, LDP uses the LDP LSR ID. Otherwise, LDP uses the LSR-ID configured by the mpls lsr-id command.
Parameters hop-number: Specifies the maximum hop count for loop detection, in the range of 1 to 32. Usage guidelines LDP adds a hop count in a label request or label mapping message. The hop count increments by 1 on each LSR. When the hop count reaches the maximum hop count configured by this command, LDP considers that a loop occurs and terminates LSP establishment. Set a proper maximum hop count according to the number of LSRs in your network.
Usage guidelines To improve security for LDP sessions, you can configure MD5 authentication for the underlying TCP connections to check the integrity of LDP messages. The local LSR and the peer LSR must have the same key. Otherwise, they cannot establish a TCP connection. After you change the MD5 authentication key, the local LSR uses the new key to reestablish an LDP session to the specified peer. For security purposes, all keys, including keys configured in plain text, are saved in cipher text.

Syntax mpls ldp enable undo mpls ldp enable Default LDP is disabled on an interface. Views Interface view Predefined user roles network-admin Usage guidelines Before you enable LDP on an interface, use the mpls ldp command in system view to enable LDP globally.
mpls ldp igp sync disable Use mpls ldp igp sync disable to disable LDP-IGP synchronization on an interface. Use undo mpls ldp igp sync disable to restore the default. Syntax mpls ldp igp sync disable undo mpls ldp igp sync disable Default LDP-IGP synchronization is enabled on an interface.
Parameters level-1: Specifies Level-1 of the IS-IS process. level-2: Specifies Level-2 of the IS-IS process. Usage guidelines LDP establishes LSPs based on the IGP optimal route. If LDP is not synchronized with IGP, MPLS traffic forwarding might be interrupted. The LDP-IGP synchronization function is used to solve the synchronization problem. After LDP-IGP synchronization is enabled, IGP advertises the actual cost of a link only when LDP convergence on the link is completed.

Using mpls ldp transport-address in interface view, you specify the transport address carried in the Link Hellos sent out of the interface. Using mpls ldp transport-address in LDP peer view, you specify the transport address carried in the Targeted Hellos sent to the LDP peer. HP recommends using the default transport address. If two LSRs have multiple links in between and you want to establish an LDP session on each link, make sure that all the links use the same transport address.
Usage guidelines LDP nonstop routing (NSR) backs up protocol states and data (including LDP session and LSP information) from the active process to the standby process. After the LDP primary process fails, the backup process seamlessly takes over the job of the primary process. The LDP peers are not aware of the LDP interruption and keep the LDP session in Operational state, so the forwarding is not interrupted.
Views LDP view, LDP-VPN instance view Predefined user roles network-admin Parameters pv-number: Specifies the path vector limit in the range of 1 to 32. Usage guidelines LDP adds LSR ID information in a label request or label mapping message. Each LSR checks whether its LSR ID is contained in the message. • If it is not, the LSR adds its own LSR ID into the message. • If it is, the LSR considers that a loop occurs and terminates LSP establishment.
To apply new parameters to an LDP session, you must use this command to reset the LDP session. Examples # Reset all LDP sessions in the public network. reset mpls ldp # Reset all LDP sessions in the VPN instance vpn1. reset mpls ldp vpn-instance vpn1 session protection Use session protection to enable session protection. Use undo session protection to disable session protection.

Views LDP view Predefined user roles network-admin Parameters peer-lsr-id: Specifies the LSR ID of a peer. Usage guidelines This command implements LDP over MPLS TE unidirectional tunnels. To implement LDP over MPLS TE, you must configure this command on the egress node of the MPLS TE tunnel, and specify the peer-lsr-id as the LSR ID of the ingress node.
The VPN instance specified by this command must have been created by the ip vpn-instance command in system view. The NSR and GR commands, the session protection command, and the targeted-peer command are available only in LDP view. All other commands available in LDP view are available in LDP-VPN instance view. Commands executed in LDP view take effect only on the public network. Commands executed in LDP-VPN instance view take effect only on the specified VPN instance.

Use undo ds-te te-class to restore the default.
Usage guidelines For a traffic trunk from a CT, the setup or/and holding priority of the LSP transporting the traffic trunk must be the priority specified for the CT in the TE class. When you configure a TE class, make sure to specify a CT-priority pair different from that in any existing TE class. When you restore the default settings for a TE class, make sure the default CT-priority pair is different from the CT-priority pair of an existing TE class.
• The prestandard mode supports only RDM. The IETF mode supports both RDM and MAM. • A device operating in prestandard mode cannot communicate with devices from some vendors. A device operating in IETF mode can communicate with devices from other vendors. Be aware of these differences and choose a proper DS-TE mode as needed. After the DS-TE mode is changed, all CRLSPs on the device are deleted and then reestablished. Examples # Configure the DS-TE mode as IETF.

Syntax fast-reroute timer interval undo fast-reroute timer Default The optimal bypass tunnel selection interval is 300 seconds. Views MPLS TE view Predefined user roles network-admin Parameters interval: Specifies the interval for selecting an optimal bypass tunnel, in the range of 0 to 604800 seconds.
undo interface tunnel-bundle number Default No tunnel bundle interface exists on a device. Views System view Predefined user roles network-admin Parameters number: Specifies the tunnel bundle interface number. The following matrix shows the value ranges for the number argument: Hardware Value range MSR2000 0 to 1023 MSR3000 0 to 2047 MSR4000 0 to 4095 Usage guidelines You can specify multiple member interfaces (MPLS TE tunnel interfaces) for a tunnel bundle interface.
Views MPLS TE view Predefined user roles network-admin Parameters interval: Specifies the interval at which IGP floods TE information, in the range of 0 to 3600 seconds. Usage guidelines When the reservable bandwidth of a link changes, IGP floods the link TE information to notify network devices of the change. You can use the mpls te bandwidth change thresholds command to configure IGP to flood only significant bandwidth changes of a link to prevent excessive IGP flooding.
Usage guidelines You can specify multiple member interfaces for a tunnel bundle interface. Traffic is shared on the member interfaces in proportion of their weights. If the member interfaces have the same weight, they will share the same load. For example, a tunnel bundle interface has three member interfaces. The weights for the member interfaces are 1, 1, and 2, respectively. The proportions of traffic forwarded by the member interfaces are 1/4, 1/4, and 1/2, respectively.
mpls te affinity-attribute Use mpls te affinity-attribute to configure an affinity for a tunnel. Use undo mpls te affinity-attribute to restore the default. Syntax mpls te affinity-attribute attribute-value [ mask mask-value ] undo mpls te affinity-attribute Default The affinity is 0x00000000, and the mask is 0x00000000. That is, a tunnel can use any link.
Related commands • display mpls te tunnel-interface • mpls te link-attribute mpls te auto-bandwidth Use mpls te auto-bandwidth to enable automatic bandwidth adjustment or output rate collection for an MPLS TE tunnel. Use undo mpls te auto-bandwidth to disable automatic bandwidth adjustment and output rate collection for an MPLS TE tunnel.
set the bandwidth adjustment interval to a value at least 3 times the sampling interval to get the accurate output rate. 4. Establishes a new CRLSP based on the adjusted bandwidth. 5. Switches traffic to the new CRLSP, and then deletes the old CRLSP. The output rate collection function collects the tunnel output rate regularly at the specified collection interval. The collected output rate is the largest of all average output rates calculated in the sampling intervals during the collection interval.
Usage guidelines The auto FRR function allows an interface to automatically set up a node-protection bypass tunnel and a link-protection bypass tunnel for each of its primary CRLSPs. The egress interface of the primary CRLSPs is the interface itself. Bypass tunnels are set up before the primary CRLSP fails. Therefore, they use extra bandwidth. To save network bandwidth, configure auto FRR only for key interfaces.
In the same tunnel interface view, the mpls te backup command cannot be used together with the mpls te reoptimization, mpls te auto-bandwidth adjustment, and mpls te resv-style ff commands. Examples # Enable hot backup for tunnel 0. system-view [Sysname] interface tunnel 0 mode mpls-te [Sysname-Tunnel0] mpls te backup hot-standby Related commands mpls te backup-path mpls te backup bandwidth Use mpls te backup bandwidth to configure the bandwidth and the CT that the bypass tunnel can protect.
forwarding for the traffic of primary CRLSP, and the occupied bandwidth is not fixed. Therefore, this type of bypass tunnel cannot protect a primary CRLSP with the bandwidth 0 or a primary CRLSP whose bandwidth exceeds the protected bandwidth. If no CT is specified, CRLSPs of all CTs can use the bypass tunnel. The bandwidth value specified is used only for calculating and determining the bandwidth protection relationship between a primary CRLSP and a bypass tunnel.
Predefined user roles network-admin Parameters preference value: Sets a preference value for the specified path, in the range of 1 to 10. The smaller the value, the higher the preference. dynamic: Uses the dynamically calculated path to establish the backup CRLSP. explicit-path path-name: Uses the specified explicit path to establish the backup CRLSP. The path-name argument specifies the name of an explicit path, a case-sensitive string of 1 to 31 characters.
Predefined user roles network-admin Parameters ct0: Specifies CT 0 for the tunnel. ct1: Specifies CT 1 for the tunnel. ct2: Specifies CT 2 for the tunnel. ct3: Specifies CT 3 for the tunnel. bandwidth: Specifies the bandwidth required by the MPLS TE tunnel, in the range of 1 to 4294967295, in kbps. Usage guidelines If you do not specify a CT for the tunnel, the tunnel is available for CT 0.
Predefined user roles network-admin Parameters down: Configures the bandwidth decrease percentage threshold that triggers the IGP to flood TE information. When the percentage of the link reservable-bandwidth decrease to the maximum link reservable bandwidth reaches or exceeds the threshold, the IGP floods the TE information and updates the TE database (TEDB). up: Configures the bandwidth increase percentage threshold that triggers the IGP to flood TE information.
Parameters associated reverse-lsp lsp-name lsp-name: Configures an associated bidirectional MPLS TE tunnel, and specifies the associated reverse CRLSP. The lsp-name argument specifies the name of a static CRLSP (the reverse CRLSP), a case-sensitive string of 1 to 15 characters. associated reverse-lsp lsr-id ingress-lsr-id tunnel-id tunnel-id: Configures an associated bidirectional MPLS TE tunnel, and specifies the associated reverse CRLSP.
[Sysname-Tunnel0] mpls te bidirectional co-routed passive reverse-lsp lsr-id 10.0.0.1 tunnel-id 1 Related commands display mpls te tunnel-interface mpls te enable (interface view) Use mpls te enable to enable MPLS TE on an interface. Use undo mpls te enable to disable MPLS TE on an interface. Syntax mpls te enable undo mpls te enable Default MPLS TE is disabled on an interface.
Default MPLS TE is disabled for an IS-IS process. Views IS-IS view Predefined user roles network-admin Parameters level-1: Enables MPLS TE for IS-IS at Level-1. level-2: Enables MPLS TE for IS-IS at Level-2. Usage guidelines If you do not specify an IS-IS level, this command enables MPLS TE for IS-IS at both Level-1 and Level-2. IS-IS TE uses a sub-TLV of the extended IS reachability TLV (type 22) to carry TE attributes.
Views OSPF area view Predefined user roles network-admin Usage guidelines OSPF TE uses Type-10 opaque LSAs to carry the TE attributes for a link. Before you configure OSPF TE, you must enable opaque LSA advertisement and reception by using the opaque-capability enable command. For more information about opaque LSA advertisement and reception, see Layer 3—IP Routing Configuration Guide. Examples # Enable MPLS TE for OSPF process 1 in OSPF area 1.
• The ingress node attempts to set up a new CRLSP. After the new CRLSP is set up successfully, traffic is forwarded on the new CRLSP. When a primary CRLSP does not need bandwidth protection, it prefers to use a bypass tunnel that does not provide bandwidth protection. No bandwidth guarantee is required after FRR. When a primary CRLSP needs bandwidth protection, it prefers to use the bypass tunnel that can protect bandwidth as much as possible to provide bandwidth guarantee after FRR.
Hardware Value range MSR2000 0 to 1023 MSR3000 0 to 2047 MSR4000 0 to 4095 Usage guidelines The protected interface (where the command is executed) is the outgoing interface of a primary CRLSP. When the outgoing interface is down or a neighbor failure is detected through the BFD or hello mechanism, the traffic of the primary CRLSP is switched to the bypass tunnel. When you use this command, follow these restrictions and guidelines: • You can specify up to three bypass tunnels for an interface.
Predefined user roles network-admin Parameters hold-time value: Specifies the period of time that IGP waits to advertise a down event of the MPLS TE tunnel, in the range of 0 to 4294967295 milliseconds. The default value is 0, which means when the MPLS TE tunnel is down, IGP immediately advertises the tunnel down event. Usage guidelines Forwarding adjacency is a method to direct traffic to an MPLS TE tunnel or tunnel bundle.
Parameters absolute value: Assigns an absolute metric to the MPLS TE tunnel or tunnel bundle, an integer in the range of 1 to 65535. An absolute metric is directly used as the MPLS TE tunnel or tunnel bundle's metric. relative value: Assigns a relative metric to the MPLS TE tunnel or tunnel bundle, an integer in the range of –10 to +10. The MPLS TE tunnel or tunnel bundle's metric is the assigned metric value plus the IGP metric.
tunnel bundle in route calculation. Other devices do not consider the MPLS TE tunnel or tunnel bundle in route calculation. If you do not specify the IGP in this command, both OSPF and IS-IS will include the MPLS TE tunnel or tunnel bundle in route calculation. On the same tunnel interface or tunnel bundle interface, the mpls te igp advertise command and the mpls te igp shortcut command cannot both take effect. The newly configured command overwrites the previous command.
The link attribute bits corresponding to the 0 bits in the affinity mask are not checked. For example, if the affinity is 0xFFFFFFF0 and the mask is 0x0000FFFF, a link is available for the tunnel when its link attribute bits meet the following requirements: • The highest 16 bits each can be 0 or 1 (no requirements). • The 17th through 28th bits must have at least one bit whose value is 1. • The lowest four bits must be 0.
Use undo mpls te max-link-bandwidth to restore the default. Syntax mpls te max-link-bandwidth bandwidth-value undo mpls te max-link-bandwidth Default The maximum link bandwidth for MPLS TE traffic is 0 kbps.

The default value is 0. Usage guidelines The device carries the bandwidth values configured by this command in IGP route advertisements.
Default The maximum reservable bandwidth of a link is 0 kbps and each BC is 0 kbps. Views Interface view Predefined user roles network-admin Parameters bandwidth-value: Specifies the maximum reservable bandwidth of the link, in the range of 1 to 4294967295 kbps. bc0 bc0-bandwidth: Specifies the value of BC 0, in the range of 1 to 4294967295 kbps. By default, BC 0 is 0 kbps. bc1 bc1-bandwidth: Specifies the value of BC 1, in the range of 1 to 4294967295 kbps. By default, BC 1 is 0 kbps.
mpls te max-reservable-bandwidth rdm Use mpls te max-reservable-bandwidth rdm to configure the BCs in IETF DS-TE RDM model. Use undo mpls te max-reservable-bandwidth rdm to restore the default.

The smaller the value, the higher the preference. dynamic: Uses the dynamically calculated path to establish the CRLSP. explicit-path path-name: Uses the specified explicit path to establish the CRLSP.
Predefined user roles network-admin Parameters igp: Uses the IGP metric. te: Uses the TE metric. Usage guidelines Each MPLS TE link has two metrics: IGP metric and TE metric. By using the two metrics, you can select different tunnels for different classes of traffic.
Parameters setup-priority: Specifies the setup priority in the range of 0 to 7. A smaller number represents a higher priority. hold-priority: Specifies the holding priority in the range of 0 to 7. A smaller number represents a higher priority. If you do not specify this argument, the holding priority is the same as the setup priority. Usage guidelines The setup priority and holding priority of an MPLS TE tunnel determines the importance of the tunnel.
Parameters label: Enables both route recording and label recording. If you do not specify this keyword, this command enables only route recording. Usage guidelines Route recording records the nodes that an MPLS TE tunnel traverses. Label recording records the label assigned by each node. The recorded information helps you know about the path used by the MPLS TE tunnel and the label distribution information, and when the tunnel fails, it helps you locate the fault.
On the same tunnel interface, the mpls te reoptimization command cannot be used together with these commands: mpls te auto-bandwidth adjustment, mpls te route-pinning, mpls te backup, and mpls te resv-style ff.

Views Tunnel interface view Predefined user roles network-admin Parameters lsp-name: Specifies a static CRLSP by its name, a case-sensitive string of 1 to 15 characters. Usage guidelines This command takes effect only when the mpls te signaling static command has been configured in tunnel interface view. Execute this command on the ingress node. The static CRLSP specified must have been created by using the static-cr-lsp ingress command.
Usage guidelines After failing to establish an MPLS TE tunnel, the tunnel ingress node waits for the tunnel setup retry interval. Then it tries to set up the tunnel until the tunnel is established successfully or the number of tunnel setup attempts reaches the maximum (configured by the mpls te retry command). If the tunnel cannot be established when the number of attempts reaches the maximum, the ingress waits for a longer period and then repeats the previous process.

sending back a message that includes the Message_ID_ACK object. If the sender does not receive a Message_ID_ACK within the retransmission interval (Rf), it retransmits the message when Rf expires and sets the next transmission interval to (1 + delta) × Rf. The sender repeats this process until it receives the Message_ID_ACK before the retransmission time expires or it has transmitted the message three times. The initial value of Rf is configured by the rsvp reduction retransmit interval command.

Usage guidelines L2VPN uses MP-BGP to exchange label blocks when creating a BGP PW. After you execute the peer enable command in BGP L2VPN address family view, BGP can exchange label blocks with the specified peer or peer group through RFC 4761 MP_REACH_NLRI. To disable the capability, execute the undo peer signaling command. Examples # Enable BGP to exchange label block information draft-kompella-ppvpn-l2vpn-03 MP_REACH_NLRI. with the peer 3.3.3.
ppp ipcp ignore local-ip Use ppp ipcp ignore local-ip to configure PPP to support IPCP negotiation without IP address. Use undo ppp ipcp ignore local-ip to restore the default. Syntax ppp ipcp ignore local-ip undo ppp ipcp ignore local-ip Default PPP does not support IPCP negotiation without IP address, and the local interface must be configured with an IP address to perform IPCP negotiation with the peer.
undo ppp ipcp proxy Default No IPCP proxy IP address is specified. Views Interface view Predefined user roles network-admin Parameters ip-address: Specifies an IPCP proxy IP address. Usage guidelines In an MPLS L2VPN interworking scenario, link layer negotiation packets cannot be delivered on the network, and Layer 2 connections cannot be established directly between CEs. Therefore, PEs must establish Layer 2 connections with the connected CEs.
Predefined user roles network-admin Parameters class-name: Specifies the name of the PW class, a case-sensitive string of 1 to 19 characters. Usage guidelines In PW class view, you can configure PW attributes such as the PW type and control word. PWs with the same attributes can use the same PW class to simplify configuration. Examples # Create a PW class named pw100 and enter PW view.
[Sysname-xcg-bbb] auto-discovery bgp [Sysname-xcg-bbb-auto] pw-class pw100 Related commands • control-word enable • display l2vpn pw-class • pw-class • pw-type pw-type Use pw-type to specify a PW type for a PW class. Use undo pw-type to restore the default. Syntax pw-type { ethernet | vlan } undo pw-type Default The PW type is VLAN. Views PW class view Predefined user roles network-admin Parameters ethernet: Specifies the PW type as Ethernet. vlan: Specifies the PW type as VLAN.
{ { • If traffic from the AC has the P-tag, the PE keeps the P-tag when the peer PE does not require the ingress to modify the P-tag or changes the P-tag to the expected value (which can be zero) when the peer PE requires the ingress to modify the P-tag. Then the PE adds the PW label and public tunnel encapsulation, and forwards the traffic through the PW.
Examples # Specify the switchover wait time as 120 seconds for the cross-connect ac2pw in the cross-connect group vpn1. system-view [Sysname] xconnect-group vpn1 [Sysname-xcg-vpn1] connection ac2pw [Sysname-xcg-vpn1-ac2pw] revertive wtr 120 Related commands display l2vpn pw route-distinguisher Use route-distinguisher to configure a route distinguisher (RD) for a BGP cross-connect group. Use undo route-distinguisher to remove the RD.
rr-filter Use rr-filter to configure the filtering of reflected L2VPN information. The route reflector only reflects the L2VPN information that contains the specified extended community number. Use undo rr-filter to restore the default. Syntax rr-filter extended-community-number undo rr-filter Default The route reflector does not filter reflected L2VPN information.
Usage guidelines After you disable a cross-connect group, all cross-connects in the group cannot provide L2VPN services. Use the shutdown command when you want to temporarily disable L2VPN (for example, to modify a cross-connect group). After the modification, use the undo shutdown command to enable the cross-connect group. This will provide L2VPN services using the new settings. Examples # Disable cross-connect group vpn2.
site 1 range 36 You can create multiple local sites for a cross-connect group. You can use the site command to increase the range value for an existing site without changing the site-id and default-offset. You cannot decrease the range value for an existing site with the site command. To decrease the range value, you must delete the site and re-create the site with the new range value. Select a large range value to reduce future modifications for VPN expansion.
Examples # Reference the tunnel policy policy1 for the auto-discovery cross-connect in the cross-connect group bbb.
Usage guidelines A local PE sets the route targets as export targets in BGP update messages when it advertises L2VPN information through the update messages to a remote peer. The peer uses its import targets to match the received export targets. If a match is found, the peer accepts the L2VPN information. Examples # Configure import route targets as 10:1 100:1 1000:1 and export route targets as 20:1 200:1 2000:1 for the BGP cross-connect group bbb.
MPLS OAM commands bfd discriminator Use bfd discriminator to configure local and remote discriminators for the BFD session used to verify PW connectivity. Use undo bfd discriminator to restore the default. Syntax bfd discriminator local local-id remote remote-id undo bfd discriminator Default No local or remote discriminators are configured for the BFD session used to verify PW connectivity. The system automatically assigns local and remote discriminators to the BFD session.
Examples # In cross-connect PW view, set both the local and remote discriminator values to 1 for the BFD session used to verify PW connectivity. system-view [Sysname] xconnect-group 1 [Sysname-xcg-1] connection 1 [Sysname-xcg-1-1] peer 22.22.2.2 pw-id 1 pw-class ttt [Sysname-xcg-1-1-22.22.2.2-1] bfd discriminator local 1 remote 1 Related commands • display l2vpn pw bfd • mpls bfd enable • vccv bfd • vccv cc display l2vpn pw bfd Use display l2vpn pw bfd to display BFD information for PWs.

and remote devices, but the mpls bfd command is not needed on the remote PE. A dynamic BFD session verifies the connectivity of a unidirectional LSP tunnel from the local device to the remote device. The source address of the BFD session is the MPLS LSR ID of the local device. Before configuring BFD for the LSP tunnel, perform the following tasks: 1. Configure an MPLS LSR ID for the local device. 2. Make sure a route is available on the remote device to reach the MPLS LSR ID.
Hardware Value range MSR2000 1 to 32 MSR3000 1 to 512 MSR4000 1 to 1024 remote remote-id: Specifies the remote discriminator value for the BFD session, in the range of 1 to 4294967295. template template-name: Specifies a BFD session parameter template by its name, a case-sensitive string of 1 to 31 characters.
