Views System view Predefined user roles network-admin Parameters vpn-instance s-vpn-instance-name: Specifies a source MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. Each VPN has its own routing table, and the configured static route is installed in the routing tables of the specified VPNs. dest-address: Specifies the destination IP address of the static route, in dotted decimal notation. mask-length/mask: Specifies the mask length or mask of the IP address.
• If the output interface is a Null 0 interface, no next hop address is required. • If the output interface is a broadcast interface (such as an Ethernet interface or a VLAN interface) that might have multiple next hops, you must specify the output interface and the next hop address at the same time. Follow these guidelines when you configure a static route: • Enabling BFD for a flapping route could worsen the situation. Therefore, use it with caution.
OSPF commands abr-summary (OSPF area view) Use abr-summary to configure a summary route on an area border router (ABR). Use undo abr-summary to remove a summary route. Syntax abr-summary ip-address { mask-length | mask } [ advertise | not-advertise ] [ cost cost ] undo abr-summary ip-address { mask-length | mask } Default No route summarization is configured on an ABR.

• To deny/permit a route with the specified destination and mask, use the rule [ rule-id ] { deny | permit } ip source sour-addr sour-wildcard destination dest-addr dest-wildcard command. The source keyword specifies the destination address of a route and the destination keyword specifies the subnet mask of the destination address. The specified subnet mask must be contiguous. Otherwise, the mask configuration does not take effect. Examples # Use ACL 2000 to filter received routes.
planned-only: Enables planned only GR. Without this keyword, this command enables both planned GR and unplanned GR. Usage guidelines GR includes planned GR and unplanned GR: • Planned GR—Manually restart OSPF or perform an active/standby switchover. Before OSPF restart or active/standby switchover, the GR restarter sends Grace-LSAs to GR helpers. • Non-planned GR—OSPF restarts or an active/standby switchover occurs because of device failure.
Views OSPF view Predefined user roles network-admin Parameters planned-only: Enable only planned GR for the GR helper. Without this keyword, this command enables both planned GR and unplanned GR for the GR helper. Usage guidelines The planned-only keyword is available only for the IETF GR helper. Examples # Enable GR helper capability for OSPF process 1.
Use undo graceful-restart interval to restore the default GR interval. Syntax graceful-restart interval interval-value undo graceful-restart interval Default The GR interval is 120 seconds. Views OSPF view Predefined user roles network-admin Parameters interval-value: Specifies the GR interval in the range of 40 to 1800 seconds. Usage guidelines The value of the GR restart interval cannot be smaller than the maximum OSPF neighbor dead time of all the OSPF interfaces. Otherwise, GR restart might fail.

Its cost is comparable with the cost of OSPF internal routes.
Default OSPF ISPF is enabled. Views OSPF view Predefined user roles network-admin Usage guidelines Upon topology changes, ISPF recomputes only the affected part of the SPT, instead of the entire SPT. Examples # Enable ISPF for OSPF process 100. system-view [Sysname] ospf 100 [Sysname-ospf-100] ispf enable log-peer-change Use log-peer-change to enable the logging of OSPF neighbor state changes. Use undo log-peer-change to disable the logging of OSPF neighbor state changes.
lsa-arrival-interval Use lsa-arrival-interval to specify the LSA arrival interval. Use undo lsa-arrival-interval to restore the default. Syntax lsa-arrival-interval interval undo lsa-arrival-interval Default The LSA arrival interval is 1000 milliseconds. Views OSPF view Predefined user roles network-admin Parameters interval: Specifies the LSA arrival interval in the range of 0 to 60000 milliseconds.
Views OSPF view Predefined user roles network-admin Parameters interval: Specifies the interval that OSPF exits overflow state, in the range of 0 to 2147483647 seconds. Usage guidelines When the number of LSAs in the LSDB exceeds the upper limit, the LSDB is in an overflow state. In this state, OSPF does not receive any external LSAs and deletes the external LSAs generated by itself to save system resources. You can configure the interval that OSPF exits overflow state.
Usage guidelines When network changes are not frequent, LSAs are generated at the minimum-interval. If network changes become frequent, the LSA generation interval is incremented by incremental-interval × 2n-2 (n is the number of generation times) each time a LSA generation occurs until the maximum-interval is reached. The minimum interval and the incremental interval cannot be greater than the maximum interval.
Syntax maximum load-balancing maximum undo maximum load-balancing Views OSPF view Predefined user roles network-admin Parameters maximum: Specifies the maximum number of ECMP routes. No ECMP load balancing is available when the number is set to 1. Usage guidelines The default setting and value range for this command depend on the setting of the max-ecmp-num command.
Parameters ip-address: Specifies the IP address of a network. wildcard-mask: Specifies the wildcard mask of the IP address. For example, the wildcard mask of mask 255.0.0.0 is 0.255.255.255. Usage guidelines This command enables OSPF on the interface attached to the specified network. The interface's primary IP address must be in the specified network. If only the interface's secondary IP address is in the network, the interface cannot run OSPF.
nssa-only: Limits the default route advertisement to the NSSA area by setting the P-bit of Type-7 LSAs to 0. By default, the P-bit of Type-7 LSAs is set to 1. If the router acts as both an ASBR and an ABR and FULL state neighbors exist in the backbone area, the P-bit of Type-7 LSAs originated by the router is set to 0. route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters.
Default The feature is enabled. Views OSPF view Predefined user roles network-admin Usage guidelines After the opaque LSA advertisement and reception is enabled, OSPF can receive and advertise Type-9, Type-10, and Type-11 opaque LSAs. Examples # Disable opaque LSA advertisement and reception. system-view [Sysname] ospf 100 [Sysname-ospf-100] undo opaque-capability ospf Use ospf to enable OSPF and enter OSPF view. Use undo ospf to disable OSPF.
[Sysname] ospf 100 router-id 10.10.10.1 [Sysname-ospf-100] ospf area Use ospf area to enable OSPF on an interface. Use undo ospf area to remove the configuration. Syntax ospf process-id area area-id [ exclude-subip ] undo ospf process-id area [ exclude-subip ] Default OSPF is not enabled on an interface. Views Interface view Predefined user roles network-admin Parameters process-id: Specifies an OSPF process by its ID in the range of 1 to 65535.

Usage guidelines Do not use OSPF FRR and BFD for OSPF at the same time. Otherwise, OSPF FRR might fail to take effect. Examples # Enable BFD for OSPF on VLAN-interface 11. system-view [Sysname] ospf [Sysname-ospf-1] area 0 [Sysname-ospf-1-area-0.0.0.0] network 192.168.0.0 0.0.255.255 [Sysname] interface vlan-interface 11 [Sysname-Vlan-interface11] ospf bfd enable ospf cost Use ospf cost to set an OSPF cost for an interface. Use undo ospf cost to restore the default.
Use undo ospf dr-priority to restore the default value. Syntax ospf dr-priority priority undo ospf dr-priority Default The router priority is 1. Views Interface view Predefined user roles network-admin Parameters priority: Specifies the router priority for the interface, in the range of 0 to 255. Usage guidelines The greater the value, the higher the priority for DR/BDR election. If a device has a priority of 0, it will not be elected as a DR or BDR.
Deleting an OSPF process that has been bound to MIB also unbinds the OSPF process from MIB, and re-binds MIB to the OSPF process with the smallest process ID.

• For Ethernet and FDDI, the network type is broadcast. • For ATM, FR, and X.25, the network type is NBMA. • For PPP, LAPB, HDLC, and POS, the network type is P2P. Views Interface view Predefined user roles network-admin Parameters broadcast: Specifies the network type as broadcast. nbma: Specifies the network type as NBMA. p2mp: Specifies the network type as P2MP. unicast: Specifies the P2MP interface to unicast OSPF packets. By default, a P2MP interface multicasts OSPF packets.
Syntax ospf prefix-suppression [ disable ] undo ospf prefix-suppression Default Prefix suppression is disabled. Views Interface view Predefined user roles network-admin Parameters disable: Disables prefix suppression on an interface. Usage guidelines To disable prefix suppression on an interface associated with an OSPF process that has been enabled with prefix suppression, execute the ospf prefix-suppression disable command on that interface. For more information, see "prefix-suppression.
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. Routers attached to the same segment must have the same dead interval. Examples # Configure the dead interval for VLAN-interface 10 as 60 seconds.
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. Syntax ospf timer poll seconds undo ospf timer poll Default The poll interval is 120 seconds on an interface. Views Interface view Predefined user roles network-admin Parameters seconds: Specifies the poll interval in the range of 1 to 2147483647 seconds. Usage guidelines When an NBMA interface finds its neighbor is down, it sends hello packets at the poll interval.
Predefined user roles network-admin Parameters interval: Specifies the LSA retransmission interval in the range of 1 to 3600 seconds. Usage guidelines After sending an LSA, an interface waits for an acknowledgement packet. If the interface receives no acknowledgement within the retransmission interval, it retransmits the LSA. To avoid unnecessary retransmissions, set an appropriate retransmission interval. For example, you can set a large retransmission interval value on a low-speed link.
peer Use peer to specify a neighbor in an NBMA or P2MP network. Use undo peer to remove the configuration. Syntax peer ip-address [ cost value | dr-priority dr-priority ] undo peer ip-address Default No neighbor is specified.

Usage guidelines Prefix Independent Convergence (PIC) enables the device to speed up network convergence by ignoring the number of prefixes. PIC applies to only inter-area routes and external routes. When both OSPF PIC and OSPF FRR are configured, OSPF FRR takes effect.
value: Specifies the preference value in the range of 1 to 255. The smaller the value, the higher the preference. Usage guidelines If multiple routing protocols find routes to the same destination, the router uses the route found by the protocol with the highest preference. Examples # Set a preference of 200 for OSPF external routes. system-view [Sysname] ospf 100 [Sysname-ospf-100] preference ase 200 # Use a routing policy to set a preference of 100.
Examples # Use a routing policy to assign the medium priority to the specified route prefixes. system-view [Sysname] ip prefix-list test index 10 permit 100.1.1.

1. Selects the route with the highest preference: { { If RFC 2328 is compatible with RFC 1583, all these routes have equal preference. If RFC 2328 is not compatible with RFC 1583, the intra-area route in a non-backbone area is preferred to reduce the burden of the backbone area. The inter-area route and intra-area route in the backbone area have equal preference. 2. Selects the route with lower cost if two routes have equal preference. 3.
after a physical interface address is selected as the router ID, or a higher interface IP address is configured as the router ID. After a router ID is changed, you must use the reset command to enable it.

This EBGP route is called shortcut route. Use undo network short-cut to cancel the configuration.
network shortcut command to configure the EBGP route to have the same preference as the local route so the EBGP route is more likely to become the optimal route. You can use the preference command to modify the preferences for external and local BGP routes. Examples # In BGP IPv4 unicast address family view, increase the preference of EBGP route 10.0.0.0/16. system-view [Sysname] bgp 100 [Sysname-bgp] address-family ipv4 unicast [Sysname-bgp-ipv4] network 10.0.0.0 255.255.0.
ip-address: Specifies a peer by its IP address. The peer must have been created. ipv6-address: Specifies a peer by its IPv6 address. The peer must have been created. Usage guidelines The COMMUNITY attribute is a group of specific data carried in update messages. A route can carry one or more COMMUNITY attribute values (each is represented by a 4-byte integer).
undo peer { group-name | ip-address } advertise-ext-community In BGP IPv6 unicast address family view: peer { group-name | ipv6-address } advertise-ext-community undo peer { group-name | ipv6-address } advertise-ext-community Default No extended community attribute is advertised to a peer or peer group.
# In BGP IPv6 unicast address family view, advertise the extended community attribute to peer group test.
number: Specifies the number of times for which the local AS number can appear, in the range of 1 to 10. The default number is 1. If the number of times for which the local AS number appears in a route is more than the specified number, BGP considers that a routing loop occurs and discards the route. Usage guidelines By default, BGP does not receive routes that contain the local AS number in the AS_PATH attribute to avoid routing loops.
Usage guidelines You can also create a peer and add it to a peer group by using the peer group command. To modify the AS number of a peer, do not execute the peer as-number command repeatedly. Instead, you must first delete the peer and configure it again. After you create a peer, you must use the peer enable command to enable BGP to exchange routing information with the specified peer. Examples # In BGP view, create BGP peer 1.1.1.1 and specify its AS number as 100.
Usage guidelines • This command applies to only a peer group with no peers in it. • When you specify an AS number for a peer group and want to add peers to it, make sure the AS number of the peers is the same as the peer group. • If you have specified no AS number for a peer group, peers added to it can use their own AS numbers. Examples # In BGP view, specify the AS number for peer group test as 100.

Configuring the preferences for BGP routes changes the possibility for the routes to become the optimal route. To reference a routing policy to set the preference, you must configure the preference with the apply preference command in the routing policy in advance. Otherwise, all matching routes use the default preference. Examples # In BGP IPv4 unicast address family view, configure preferences for EBGP, IBGP, and local routes as 20, 20, and 200.
Predefined user roles network-admin Usage guidelines When a route reflector is configured, and the clients of a route reflector are fully meshed, route reflection is unnecessary because it consumes more bandwidth resources. You can use the undo reflect between-clients command to disable route reflection instead of modifying network configuration or changing network topology. After route reflection is disabled between clients, routes can still be reflected between a client and a non-client.

Use undo snmp-agent trap enable bgp to disable SNMP notifications for BGP. Syntax snmp-agent trap enable bgp undo snmp-agent trap enable bgp Default SNMP notifications for BGP are enabled.
Predefined user roles network-admin Usage guidelines After the summary automatic command is configured, BGP summarizes IGP subnets redistributed by the import-route command. Automatic summary routes can be manually summarized, but cannot be added to the IP routing table. Examples # In BGP IPv4 unicast address family view, configure automatic route summarization for redistributed IGP subnet routes.
Usage guidelines After establishing a BGP session, two routers send keepalive messages at the specified keepalive interval to each other to keep the session. If a router receives no keepalive or update message from the peer within the holdtime, it tears down the session. Use the timer command to configure the keepalive interval and holdtime for all BGP peers. Use the peer timer command to configure the keepalive interval and holdtime for a peer or peer group.

cost cost: Specifies a cost for redistributed routes, in the range of 1 to 16777214. The default is 1. nssa-only: Limits the route advertisement to the NSSA area by setting the P-bit of Type-7 LSAs to 0. By default, the P-bit of Type-7 LSAs is set to 1. If the router acts as both an ASBR and an ABR and FULL state neighbors exist in the backbone area, the P-bit of Type-7 LSAs originated by the router is set to 0. This keyword applies to NSSA routers.
Views OSPFv3 view Predefined user roles network-admin Usage guidelines This feature enables the device to deliver logs about neighbor state changes to its information center, which processes logs according to user-defined output rules (whether to output logs and where to output). For more information about the information center, see Network Management and Monitoring Configuration Guide. Examples # Disable the logging of neighbor state changes for OSPFv3 process 100.
The minimum interval and the incremental interval cannot be greater than the maximum interval. Examples # Configure the maximum LSA generation interval as 2 seconds, minimum interval as 100 milliseconds, and incremental interval as 100 milliseconds.
nssa Use nssa to configure the current area as an NSSA area. Use undo nssa to restore the default.
