{ { { { If the outgoing interface is a Null 0 interface, no next hop address is required. If the outgoing interface is a point-to-point interface, a PPP serial interface for example, you can specify only the outgoing interface. You do not need to change the configuration of the route even if the peer address is changed. If the outgoing interface is an NBMA interface or point-to-multipoint (P2MP) interface, an X.
undo ip route-static default-preference Default The default preference of static routes is 60. Views System view Default command level 2: System level Parameters default-preference-value: Specifies a default preference for static routes, in the range of 1 to 255. Usage guidelines If no preference is specified for a static route, the default preference is used. When the default preference is re-configured, it applies to newly added static routes only.
Usage guidelines Configuring static route FRR needs to reference a routing policy, which specifies a backup next hop with the apply fast-reroute backup-interface command. For more information about the command and routing policy configurations, see Layer 3—IP Routing Configuration Guide. Static route FRR takes effect only for static routes that have both the outgoing interface and next hop specified. Do not use static route FRR and BFD (for static route) at the same time.
RIP configuration commands checkzero Use checkzero to enable zero field check on RIPv1 messages. Use undo checkzero to disable zero field check. Syntax checkzero undo checkzero Default The zero field check function is enabled. Views RIP view Default command level 2: System level Usage guidelines After the zero field check is enabled, the router discards RIPv1 messages in which zero fields are non-zero. If all messages are trusted, disable this feature to reduce the processing time of the CPU.
Default command level 2: System level Parameters value: Specifies a default metric for redistributed routes, in the range of 0 to 16. Usage guidelines When you use the import-route command to redistribute routes from other protocols without specifying a metric, the metric specified by the default cost command applies. Examples # Configure the default metric for redistributed routes as 3.
[Sysname] rip 100 [Sysname-rip-100] default-route only cost 2 Related commands rip default-route display rip Use display rip to display the current status and configuration information of the specified RIP process. Syntax display rip [ process-id | vpn-instance vpn-instance-name ] [ | { begin | exclude | include } regular-expression ] Views Any view Default command level 1: Monitor level Parameters process-id: Specifies a RIP process by its ID in the range of 1 to 65535.

Aging Total number of aging routes learned from the specified neighbor.
Usage guidelines RIP FRR is only effective for non-recursive RIP routes that are learned from directly connected neighbors. Do not use RIP FRR and BFD for RIP at the same time; otherwise, RIP FRR might fail to take effect. Examples # Enable RIP FRR and reference routing policy frr to specify a backup next hop. system-view [Sysname] bfd echo-source-ip 1.1.1.1 [Sysname] ip ip-prefix abc index 10 permit 100.1.1.
Usage guidelines If a protocol is specified, RIP filters only the routes redistributed from the specified routing protocol. Otherwise, RIP filters all routes to be advertised. If interface-type interface-number is specified, RIP filters only the routes advertised by the specified interface. Otherwise, RIP filters routes advertised by all RIP interfaces.
Syntax filter-policy { acl-number | gateway ip-prefix-name | ip-prefix ip-prefix-name [ gateway ip-prefix-name ] } import [ interface-type interface-number ] undo filter-policy import [ interface-type interface-number ] Default RIP does not filter received routes. Views RIP view Default command level 2: System level Parameters acl-number: Specifies an ACL by its number in the range of 2000 to 3999 to filter received routes.
[Sysname-acl-adv-3000] quit [Sysname] rip 1 [Sysname-rip-1] filter-policy 3000 import Related commands • acl (ACL and QoS Command Reference) • ip ip-prefix host-route Use host-route to enable host route reception. Use undo host-route to disable host route reception. Syntax host-route undo host-route Default Receiving host routes is enabled. Views RIP view Default command level 2: System level Usage guidelines In some cases, a router might receive many host routes from the same network segment.
Default RIP does not redistribute routes from other routing protocols. Views RIP view Default command level 2: System level Parameters protocol: Specifies a routing protocol from which to redistribute routes. It can be bgp, direct, isis, ospf, rip, or static. process-id: Specifies a process by its ID in the range of 1 to 65535. The default is 1. This argument is available only when the protocol is isis, rip, or ospf. all-processes: Enables route redistribution from all the processes of a protocol.
Syntax maximum load-balancing number undo maximum load-balancing Default The maximum number of ECMP routes is 8. Views RIP view Default command level 2: System level Parameters number: Specifies the maximum number of ECMP routes, in the range of 1 to 8. Examples # Specify the maximum number of ECMP routes as 2. system-view [Sysname] rip [Sysname-rip-1] maximum load-balancing 2 network Use network to enable RIP on the interface attached to the specified network.
If a physical interface is attached to multiple networks, you cannot advertise these networks in different RIP processes. Examples # Enable RIP on the interface attached to the network 129.102.0.0. system-view [Sysname] rip 100 [Sysname-rip-100] network 129.102.0.0 output-delay Use output-delay to configure the maximum RIP packets that can be sent at the specified interval for all interfaces under the RIP process. Use undo output-delay to restore the default.
Default No neighbor is specified. Views RIP view Default command level 2: System level Parameters ip-address: Specifies the IP address of a RIP neighbor, in dotted decimal notation. Usage guidelines You need not use the peer ip-address command when the neighbor is directly connected; otherwise the neighbor might receive both the unicast and multicast (or broadcast) of the same routing information. Examples # Specify to send unicast updates to peer 202.38.165.1.
• If no preference is set by the routing policy, the preference of all RIP routes is set by the preference command. Examples # Set the RIP route preference to 120. system-view [Sysname] rip 1 [Sysname-rip-1] preference 120 reset rip process Use reset rip process to reset the specified RIP process. Syntax reset rip process-id process Views User view Default command level 1: Monitor level Parameters process-id: Specifies a RIP process by its ID in the range of 1 to 65535.
reset rip 100 statistics rip Use rip to create a RIP process and enter RIP view. Use undo rip to disable a RIP process. Syntax rip [ process-id ] [ vpn-instance vpn-instance-name ] undo rip [ process-id ] [ vpn-instance vpn-instance-name ] Default No RIP process runs. Views System view Default command level 2: System level Parameters process-id: Specifies a RIP process by its ID in the range of 1 to 65535. The default is 1. vpn-instance vpn-instance-name: Specifies an MPLS L3VPN.
Views Interface view Default command level 2: System level Parameters md5: Specifies the MD5 cipher authentication mode. rfc2082: Uses the message format defined in RFC 2082. cipher: Sets a ciphertext authentication key or password. If this keyword is not specified, you set a plaintext authentication key or password. key-string: Specifies the MD5 key string. This argument is case sensitive. It must be a plaintext string of 1 to 16 characters, or a ciphertext string of 33 to 53 characters.
Default A RIP interface is not enabled with BFD. Views Interface view Default command level 2: System level Usage guidelines BFD echo-mode detection only works for a RIP neighbor one hop away. Using the undo peer command does not delete the neighbor relationship at once and cannot bring down the BFD session at once. The rip bfd enable command and the rip bfd enable destination command are mutually exclusive and cannot be configured on a device at the same time.
Examples # Enable BFD on GigabitEthernet 0/0/1 for a specified destination 202.38.165.1. system-view [Sysname] interface gigabitethernet 0/0/1 [Sysname-GigabitEthernet0/0/1] rip bfd enable destination 202.38.165.1 rip default-route Use rip default-route to configure the RIP interface to advertise a default route with the specified metric. Use undo rip default-route to disable the RIP interface from sending a default route.
Syntax rip input undo rip input Default An interface is enabled to receive RIP messages. Views Interface view Default command level 2: System level Examples # Enable GigabitEthernet 2/1/1 to receive RIP messages. system-view [Sysname] interface gigabitethernet 2/1/1 [Sysname-GigabitEthernet2/1/1] rip input rip metricin Use rip metricin to configure the interface to add a metric to the routes it receives. Use undo rip metricin to restore the default.
• Routes matching the policy are added with the metric specified in the apply cost command configured in the policy. Routes not matching it are added with the metric specified in the rip metricin command. The metric specified in the rip metricin command cannot be changed by using the + or – keyword—used to add or reduce a metric—specified in the apply cost command. For more information about the apply cost command, see "Routing policy configuration commands.
• If the apply cost command is not configured in the policy, all the advertised routes are added with the metric specified in the rip metricout command.

Use undo rip version to remove the specified RIP version.
When RIPv2 runs on the interface in multicast mode, the interface can perform the following operations: • Sends RIPv2 multicast messages. • Receives RIPv2 broadcast, multicast, and unicast messages. Examples # Configure GigabitEthernet 2/1/1 to broadcast RIPv2 messages.
undo summary Default Automatic RIPv2 summarization is enabled. Views RIP view Default command level 2: System level Usage guidelines Enabling automatic RIPv2 summarization can reduce the size of the routing table to enhance the scalability and efficiency of large networks. Examples # Disable RIPv2 automatic summarization. system-view [Sysname] rip [Sysname-rip-1] undo summary Related commands rip version timers Use timers to configure RIP timers.
Usage guidelines RIP is controlled by the following timers: • Update timer—Defines the interval between routing updates. • Timeout timer—Defines the route aging time. If no routing update related to a route is received after the aging time, the metric of the route is set to 16 in the routing table. • Suppress timer—Defines how long a RIP route stays in suppressed state. When the metric of a route is 16, the route enters the suppressed state.
version Use version to specify a global RIP version. Use undo version to remove the configured global RIP version. Syntax version { 1 | 2 } undo version Default If an interface has a RIP version specified, the RIP version takes effect; if it has no RIP version specified, it can send RIPv1 broadcasts, and receive RIPv1 broadcasts and unicasts, and RIPv2 unicasts, broadcasts, and multicasts.

Views Interface view Default command level 2: System level Parameters value: Specifies an OSPF cost in the range of 0 to 65535 for a loopback interface and 1 to 65535 for other interfaces.
Default command level 2: System level Parameters priority: Specify the DR priority for the interface, in the range of 0 to 255. Usage guidelines The bigger the value, the higher the priority. If a device has a priority of 0, it will not be elected as a DR or BDR. Examples # Set the DR priority on an interface to 8.
Use undo ospf mtu-enable to restore the default. Syntax ospf mtu-enable undo ospf mtu-enable Default An interface adds a MTU of 0 into DD packets, which means no real MTU is added. Views Interface view Default command level 2: System level Usage guidelines After a virtual link is established through a Virtual-Template or Tunnel, two devices on the link from different vendors might have different MTU values. To make them consistent, set the attached interfaces’ MTU to the default value 0.
unicast: Specifies the P2MP interface to unicast OSPF packets. By default, a P2MP interface multicasts OSPF packets. p2p: Specifies the network type as P2P. Usage guidelines • For Ethernet, and FDDI, the default network type is broadcast. • For ATM, FR, and X.25, the default network type is NBMA. • For PPP, LAPB, HDLC, and POS, the default network type is P2P. If a router on a broadcast network does not support multicast, configure the network type for the connected interfaces as NBMA.
Usage guidelines A device that has OSPF NSR enabled cannot act as a GR restarter. The graceful-restart command and the ospf non-stop-routing command are mutually exclusive and cannot be configured on a device at the same time. Examples # Enable OSPF NSR. system-view [Sysname] ospf non-stop-routing ospf packet-process prioritized-treatment Use ospf packet-process prioritized-treatment to enable OSPF to give priority to receiving and processing Hello packets.
Default command level 2: System level Parameters seconds: Specifies the dead interval in seconds, in the range of 1 to 2147483647. Usage guidelines If an interface receives no hello packet from a neighbor within the dead interval, the interface considers the neighbor down. The dead interval on an interface is at least four times the hello interval. Any two routers attached to the same segment must have the same dead interval. Examples # Configure the dead interval on an interface as 60 seconds.
Related commands ospf timer dead ospf timer poll Use ospf timer poll to set the poll interval on an NBMA interface. Use undo ospf timer poll to restore the default value.

Examples # Clear OSPF statistics. reset ospf counters reset ospf process Use reset ospf process to reset all OSPF processes or a specified process.
Views User view Default command level 2: System level Parameters process-id: Specifies an OSPF process by its ID in the range of 1 to 65535. Usage guidelines If no process ID is specified, the command restarts route redistribution for all OSPF processes. Examples # Restart OSPF route redistribution. reset ospf redistribution rfc1583 compatible Use rfc1583 compatible to enable compatibility with RFC 1583. Use undo rfc1583 compatible to disable the function.
Syntax router id router-id undo router id Default No global router ID is configured. Views System view Default command level 2: System level Parameters router-id: Router ID, in the form of a dotted decimal IPv4 address. Usage guidelines Some routing protocols use a router ID to identify a device. You can configure a global router ID, which is used by routing protocols that have no router ID configured.
Default command level 2: System level Parameters interface-type interface-number: Specifies an interface by its type and number. all: Specifies all interfaces. Usage guidelines A disabled interface is a passive interface that cannot send any hello packets. To disable a network from receiving OSPF routes, you can issue this command on the interface connected to the network. Examples # Disable an interface from sending OSPF packets.
lsdbapproachoverflow: Information about cases approaching LSDB overflow. lsdboverflow: LSDB overflow information. maxagelsa: LSA max age information. nbrstatechange: Neighbor state change information. originatelsa: Information about LSAs originated locally. vifauthfail: Virtual interface authentication failure information. vifcfgerror: Virtual interface configuration error information. virifauthfail: Virtual interface authentication failure information.

Use undo isis peer-ip-ignore to restore the default. Syntax isis peer-ip-ignore undo isis peer-ip-ignore Default The PPP interface checks the peer's IP address upon receiving a hello packet. Views Interface view Default command level 2: System level Usage guidelines An IS-IS PPP interface requires the sender of a hello packet must be on the same network segment as it. Otherwise, it discards the hello packet. You can use the isis peer-ip-ignore command to disable this restriction.
[Sysname-GigabitEthernet4/0/1] isis silent isis small-hello NOTE: This command is not available in loopback interface view. Use isis small-hello to configure the interface to send small hello packets without CLVs. Use undo isis small-hello to restore the default. Syntax isis small-hello undo isis small-hello Default An interface sends standard hello packets. Views Interface view Default command level 2: System level Examples # Configure the GigabitEthernet 4/0/1 interface to send small Hello packets.
Default command level 2: System level Parameters seconds: Specifies on the DIS of a broadcast network the interval for sending CSNP packets. The value range is 1 to 600 seconds. level-1: Applies the interval to Level-1. level-2: Applies the interval to Level-2. Usage guidelines This command only applies to the DIS of a broadcast network, which sends CSNP packets periodically for LSDB synchronization. If no level is specified, the CSNP interval applies to both Level-1 and Level-2.
Usage guidelines Level-1 and Level-2 hello packets are sent independently on a broadcast network, so you need to specify an interval for each of the two levels. On a P2P link, Level-1 and Level-2 packets are both sent in P2P hello packets, and you need not specify an interval for each of the two levels. You can configure keywords level-1 and level-2 only on broadcast interfaces. Before you do that, enable IS-IS on the interface.
Usage guidelines With the IS-IS hello multiplier configured, a router can uses hello packets to notify its neighbor router of the adjacency hold time (hello multiplier times hello interval). If the neighbor router receives no hello packets from this router within the hold time, it declares the adjacency down. You can adjust the adjacency hold time by changing the hello multiplier or the hello interval on an interface.
count: Specifies the maximum number of link-state packets to be sent at one time, in the range of 1 to 1000. The default is 5. Examples # Configure the interval as 500 milliseconds for sending LSPs on interface GigabitEthernet 4/0/1. system-view [Sysname] interface GigabitEthernet 4/0/1 [Sysname-GigabitEthernet4/0/1] isis timer lsp 500 Related commands isis timer retransmit isis timer retransmit NOTE: This command is not available in loopback interface view.

[Sysname-isis-1] log-peer-change lsp-fragments-extend Use lsp-fragments–extend to enable an LSP fragment extension mode for a level. Use undo lsp-fragments–extend to disable LSP fragment extension for a level. Syntax lsp-fragments-extend [ [ level-1 | level-1-2 | level-2 ] | [ mode-1 | mode-2 ] ] * undo lsp-fragments-extend Default LSP fragment extension is disabled. Views IS-IS view Default command level 2: System level Parameters level-1: Applies the fragment extension mode to Level-1 LSPs.
Default The maximum size of generated Level-1 and Level-2 LSPs is 1497 bytes. Views IS-IS view Default command level 2: System level Parameters size: Specifies the maximum size of LSP packets, in the range of 512 to 16384 bytes. level-1: Applies the size to Level-1 LSP packets. level-2: Applies the size to Level-2 LSP packets. Usage guidelines If neither Level-1 nor Level-2 is specified in the command, the configured maximum size applies to the current IS-IS level.
maximum load-balancing (IS-IS view) Use maximum load-balancing to configure the maximum number of equal-cost multi-path (ECMP) routes for load balancing. Use undo maximum load-balancing to restore the default. Syntax [ ipv4-unicast topology-name ] maximum load-balancing number undo [ ipv4-unicast topology-name ] maximum load-balancing Default The maximum number of ECMP routes is 8.
Default command level 2: System level Parameters topology-name: Specifies a topology by its name, a case-sensitive string of 1 to 31 characters. topology-number: Specifies a topology by its number in the range of 6 to 4095. Usage guidelines This command takes effect only after you enable the IPv4 unicast topology for the IPv4 address family and set the cost style to wide, compatible, or wide-compatible for the system. Examples # Enable IPv4 unicast topology voice (4000) for IS-IS process 1.
For example, a NET is ab.cdef.1234.5678.9abc.00, where area ID is ab.cdef, system ID is 1234.5678.9abc, and SEL is 00. Examples # Specify the NET as 10.0001.1010.1020.1030.00, of which 10.0001 is the area ID and 1010.1020.1030 is the system ID. system-view [Sysname] isis 1 [Sysname-isis-1] network-entity 10.0001.1010.1020.1030.00 Related commands • isis • isis enable non-stop-routing Use non-stop-routing to enable IS-IS NSR. Use undo non-stop-routing to disable IS-IS NSR.
undo non-stop-routing interval Default The NSR interval is 0 seconds—no NSR interval is set. Views IS-IS view Default command level 2: System view Parameters interval-value: Specifies the NSR interval in the range of 30 to 1800 seconds. The NSR interval refers to the expected interval of an active/standby main board switchover on a device.
Usage guidelines If a routing policy is specified in this command, the preference (if any) set by the routing policy applies to those matched routes. Other routes use the preference set by the preference command. When a router runs multiple routing protocols at the same time, the system configures a preference to each routing protocol. If several protocols find routes to the same destination, the route of the routing protocol with the highest preference is selected.
Syntax reset isis all [ process-id | vpn-instance vpn-instance-name ] Default No data structure information is cleared. Views User view Default command level 2: System level Parameters process-id: Clears the data structure information of an IS-IS process numbered from 1 to 65535. vpn-instance vpn-instance-name: Clears the data structure information of the MPLS L3VPN. vpn-instance-name is a case-sensitive string of 1 to 31 characters.
Usage guidelines This command is used when you need to re-establish an IS-IS neighbor relationship. Examples # Clear the data structure information of the neighbor with the system ID 0000.0c11.1111. reset isis peer 0000.0c11.1111 set-overload Use set-overload to set the overload bit. Use undo set-overload to clear the overload bit.
If the on-startup keyword is specified, IS-IS sets the overload bit upon system startup and keeps it set within the timeout2 interval. Examples # Set overload flag on the current router. system-view [Sysname] isis 1 [Sysname-isis-1] set-overload summary (IS-IS view) Use summary to configure a summary route. Use undo summary to remove a summary route.
You can summarize multiple contiguous networks into a single network to reduce the size of the routing table, as well as that of LSP and LSDB generated by the router. It is allowed to summarize native IS-IS routes and redistributed routes. After summarization, the cost of the summary route is the smallest cost of those summarized routes. The router summarizes only routes in local LSPs. Examples # Configure a summary route of 202.0.0.0/8. system-view [Sysname] isis 1 [Sysname-isis-1] summary 202.
• If the maximum, initial, and second wait intervals are specified: { { { IS-IS waits the initial interval before generating the first LSP. If the network topology is unstable—triggers occur at intervals shorter than the maximum interval, IS-IS waits the second-wait-interval before generating the second LSP and penalty is applied on the wait interval before generating the next LSP.
timer lsp-refresh Use timer lsp-refresh to configure the LSP refresh interval. Use undo timer lsp-refresh to restore the default. Syntax timer lsp-refresh seconds undo timer lsp-refresh Default The default LSP refresh interval is 900 seconds. Views IS-IS view Default command level 2: System level Parameters seconds: Specifies the LSP refresh interval in seconds, in the range of 1 to 65534.
Default command level 2: System level Parameters maximum-interval: Specifies the maximum SPF calculation interval, in the range of 1 to 120 seconds. initial-interval: Specifies the wait interval before the first SPF calculation, in the range of 10 to 60000 milliseconds. second-wait-interval: Specifies the wait interval before the second SPF calculation, in the range of 10 to 60000 milliseconds.
Views IS-IS view Default command level 2: System level Parameters virtual-system-id: Virtual system ID of the IS-IS process. Usage guidelines Up to 50 virtual system IDs can be configured for the IS-IS process. Examples # Set a virtual system ID of 2222.2222.2222 for IS-IS process 1. system-view [Sysname] isis 1 [Sysname-isis-1] virtual-system 2222.2222.
BGP configuration commands For more information about routing policy configuration commands in this document, see "Routing policy configuration commands." aggregate Use aggregate to create a summary route in the BGP routing table. Use undo aggregate to remove a summary route.
Keywords Function detail-suppressed This keyword does not suppress the summary route, but it suppresses the advertisement of all the more specific routes. To summarize only some specific routes, use the peer filter-policy command. suppress-policy Used to create a summary route and suppress the advertisement of some summarized routes. If you want to suppress some routes selectively and leave other routes still advertised, use the if-match clause of the route-policy command.
Usage guidelines During BGP network optimization or upgrade, each change of BGP routing policies triggers route refreshing, which burdens BGP routers and the network. To resolve this issue, use the undo auto-refresh enable command to disable the policies from automatically taking effect. After modifying all policies, execute the refresh bgp or reset bgp command to make the new policies take effect. Examples # Disable BGP routing policies from automatically taking effect.
system-view [Sysname] bgp 100 [Sysname-bgp] balance ibgp 2 # In BGP view, set the number of EBGP ECMP routes to 2. system-view [Sysname] bgp 100 [Sysname-bgp] balance ebgp 2 # In BGP-VPN instance view, set the number of BGP ECMP routes to 2. (The VPN has been created.) system-view [Sysname] bgp 100 [Sysname-bgp] ipv4-family vpn-instance vpn1 [Sysname-bgp-ipv4-vpn1] balance 2 # In BGP-VPN instance view, set the number of IBGP ECMP routes to 2.

[Sysname] bgp 100 [Sysname-bgp] bestroute as-path-neglect # In BGP-VPN instance view, ignore AS_PATH in route selection. (The VPN has been created.) system-view [Sysname] bgp 100 [Sysname-bgp] ipv4-family vpn-instance vpn1 [Sysname-bgp-ipv4-vpn1] bestroute as-path-neglect bestroute compare-med (BGP/BGP-VPN instance view) Use bestroute compare-med to enable the comparison of MEDs for routes on a per-AS basis. Use undo bestroute compare-med to disable this comparison.
Default The comparison is not enabled. Views BGP view, BGP-VPN instance view Default command level 2: System level Usage guidelines The system only compares MED values for paths from peers within the confederation. Paths from external ASs are advertised throughout the confederation without MED comparison. Examples # In BGP view, enable the comparison of the MED for paths from peers within the confederation.
[Sysname-bgp] compare-different-as-med (BGP/BGP-VPN instance view) Use compare-different-as-med to enable the comparison of the MED for paths from peers in different ASs. Use undo compare-different-as-med to disable the comparison. Syntax compare-different-as-med undo compare-different-as-med Default The comparison is disabled.
Views BGP view Default command level 2: System level Parameters as-number: Specifies the number of the AS that contains multiple sub-ASs, in the range of 1 to 4294967295. Usage guidelines Configuring a confederation can reduce IBGP connections in a large AS. You can split the AS into several sub-ASs, and each sub-AS remains fully meshed. These sub-ASs form a confederation. Key IGP attributes of a route, such as the next hop, MED, or local preference, are not discarded when crossing each sub-AS.
Views BGP view Default command level 2: System level Usage guidelines All devices should be configured with this command to interact with those nonstandard devices in the confederation. Examples # AS 100 contains routers not compliant with RFC 3065 and comprises two sub-ASs, 64000 and 65000.
If the undo confederation peer-as command without the as-number-list argument is used, all confederation peer sub-ASs are removed. Examples # Specify confederation peer sub ASs 2000 and 2001. system-view [Sysname] bgp 100 [Sysname-bgp] confederation id 10 [Sysname-bgp] confederation peer-as 2000 2001 Related commands • confederation id • confederation nonstandard dampening (BGP/BGP-VPN instance view) Use dampening to enable BGP route dampening, configure dampening parameters, or both.
Usage guidelines The command dampens only EBGP routes rather than IBGP routes. Examples # In BGP view, configure BGP route dampening. system-view [Sysname] bgp 100 [Sysname-bgp] dampening 15 15 1000 2000 10000 # In BGP-VPN instance view, configure BGP route dampening. (The VPN has been created.
Examples # Enable the default use of IPv4 unicast address family for the peers that are established using the peer as-number command. system-view [Sysname] bgp 100 [Sysname-bgp] default ipv4-unicast default local-preference (BGP/BGP-VPN instance view) Use default local-preference to configure the default local preference. Use undo default local-preference to restore the default value.
Syntax default med med-value undo default med Default The default med-value is 0. Views BGP view, BGP-VPN instance view Default command level 2: System level Parameters med-value: Specifies the default MED value in the range of 0 to 4294967295. Usage guidelines Multi-exit discriminator (MED) is an external metric for routes. Different from local preference, MED is exchanged between ASs and stays in the AS once it enters the AS. The route with a lower MED is preferred.
Default command level 2: System level Usage guidelines You must use the default-route imported command together with the import-route command to redistribute default routes from other protocols. Examples # In BGP view, allow default route redistribution from OSPF into BGP. system-view [Sysname] bgp 100 [Sysname-bgp] default-route imported [Sysname-bgp] import-route ospf 1 # In BGP-VPN instance view, enable redistributing default route from OSPF into BGP. (The VPN has been created.

Syntax router-id router-id undo router-id Views BGP view Default command level 2: System level Parameters router-id: Router ID in IP address format. Usage guidelines To run IPv6 BGP protocol, a router must have a router ID, an unsigned 32-bit integer and the unique ID of the router in the AS. Specify a router ID manually, or the system selects the highest IPv4 address among loopback interface addresses as the router ID.
Parameters None Usage guidelines With this feature enabled and when a non-BGP router is responsible for forwarding packets in an AS, IPv6 BGP speakers in the AS cannot advertise routing information to other ASs unless all routers in the AS know the latest routing information. Examples # Enable the route synchronization between IPv6 BGP and IGP.
If neither the holdtime interval nor the keepalive interval is configured as 0, the holdtime interval must be at least three times the keepalive interval. The configured timers apply to all IPv6 BGP peers, but they become valid for an IPv6 BGP peer only after the relevant IPv6 BGP connection is reset. After this command is executed, no peer connection is closed at once. The configured hold time is used for negotiation when a peer relationship is reestablished.

Use undo ip ip-prefix to remove an IPv4 prefix list or an item of it.
Usage guidelines An IPv4 prefix list is used to filter IPv4 addresses. It can contain multiple items, each of which specifies a range of IPv4 prefixes. The relation between the items is logic OR. If an item is passed, the IPv4 prefix list is passed. If no item is passed, the IP prefix list cannot be passed. The IP prefix range is determined by mask-length and [ min-mask-length, max-mask-length ].
Syntax apply ipv6 next-hop ipv6-address undo apply ipv6 next-hop Default No next hop address is configured for IPv6 routing information. Views Routing policy view Default command level 2: System level Parameters ipv6-address: Specifies the next hop IPv6 address. Usage guidelines This command cannot set a next hop for redistributed routes. Examples # Configure node 10 of routing policy policy1 to configure next hop 3ffe:506::1 for IPv6 routes matching AS path list 1.
Usage guidelines If no IPv6 prefix list is specified, this command displays the statistics for all IPv6 prefix lists. Examples # Display the statistics for all IPv6 prefix lists. display ip ipv6-prefix Prefix-list6 abc Permitted 0 Denied 0 index: 10 permit ::/0 index: 20 permit ::/1 ge 1 le 128 Table 110 Command output Field Description Prefix-list6 Name of the IPv6 prefix list. Permitted Number of routes matching the criterion.

Examples # Configure node 10 of routing policy policy1 to permit routing information whose next hop matches IPv6 prefix list p1.
The length relation is mask-length <= min-mask-length <= max-mask-length <= 128. If only the min-prefix-length is specified, the prefix length range is [ min-prefix-length, 128 ]. If only the max-prefix-length is specified, the prefix length range is [ prefix-length, max-prefix-length ]. If both the min-prefix-length and max-prefix-length are specified, the prefix length range is [ min-prefix-length, max-prefix-length ].
