Table 4 Command output

Field

Description

Max ECMP

Maximum number of ECMP routes supported by the system.

Max Active Route

Maximum number of supported routes.

Remain Active Route

Number of the remaining inactive routes.

Threshold value xxx

Alarm threshold of active routes specified by using the routing-table limit command in a VPN instance:

·     Threshold value of active routes alert—This field is displayed when the alarm threshold is specified by using the routing-table limit number simply-alert command. When the number of active routes exceeds the alarm threshold, the system logs the event and sends traps but still accepts active routes.

·     Threshold value percentage of max active routes—This field is displayed when the routing-table limit number simply-alert command is not configured or when the alarm threshold is specified by using the routing-table limit number warn-threshold command. The value range for the alarm threshold is 1 to 100 in percentage. When the percentage of active routes exceeds the alarm threshold, the system logs the event and sends traps but still accepts active routes. If the number of active routes reaches the maximum number, no more routes can be added. The percentage of active routes equals the number of active routes divided by the maximum number of active routes supported in a VPN instance, and multiplied by 100.

Predefined user roles

network-admin

Parameters

seconds: Specifies the maximum lifetime for routes in the FIB, in the range of 0 to 6000 seconds. When this argument is set to 0, FIB entries immediately age out after a protocol or RIB process switchover.

Usage guidelines

When a protocol or RIB process switchover occurs and GR or NSR is not configured, FIB entries age out after the time specified in this command.

Examples

# Set the maximum lifetime for IPv4 routes in the FIB to 60 seconds.

<Sysname> system-view

[Sysname] rib

[Sysname-rib] address-family ipv4

[Sysname-rib-ipv4] fib lifetime 60

inter-protocol fast-reroute

Use inter-protocol fast-reroute to enable IPv4 or IPv6 RIB inter-protocol FRR.

Use undo inter-protocol fast-reroute to disable IPv4 or IPv6 RIB inter-protocol FRR.

Syntax

inter-protocol fast-reroute [ vpn-instance vpn-instance-name ]

undo inter-protocol fast-reroute [ vpn-instance vpn-instance-name ]

Default

Inter-protocol FRR is disabled.

Views

RIB IPv6 address family view

Predefined user roles

network-admin

Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, the command enables IPv4 or IPv6 RIB inter-protocol FRR for the public network.

Usage guidelines

This command allows a device to perform fast rerouting between routes of different protocols. A backup next hop is automatically selected to reduce the service interruption time caused by unreachable next hops. When the next hop of the primary link fails, the traffic is redirected to the backup next hop.

This command uses the next hop of a route from a different protocol as the backup next hop for the faulty route, which might cause loops.

Inter-protocol FRR cannot select a backup next hop from routes in the RIB that have the same next hop, output interface, and destination as those of the faulty route.

Examples

# Enable IPv4 RIB inter-protocol FRR for the public network.

<Sysname> system-view

[Sysname] rib

[Sysname-rib] address-family ipv4

[Sysname-rib-ipv4] inter-protocol fast-reroute

protocol lifetime

Use protocol lifetime to set the maximum lifetime for IPv4 or IPv6 routes and labels in the RIB.

Use undo protocol lifetime to restore the default.

Syntax

protocol protocol [ instance instance-name ] lifetime seconds

undo protocol protocol [ instance instance-name ] lifetime

Default

The maximum lifetime for IPv4 or IPv6 routes and labels in the RIB is 480 seconds.

Parameters

protocol: Specifies a routing protocol.

instance instance-name: Specifies a BGP instance by its name, a case-sensitive string of 1 to 31 characters. This argument applies only to the BGP protocol. If you do not specify a BGP instance, this command sets the maximum lifetime for all BGP routes and labels in the RIB.

seconds: Specifies the maximum lifetime for routes and labels in the RIB, in the range of 1 to 6000 seconds.

Usage guidelines

When GR is enabled, make sure the protocol can complete GR and install all route entries to the RIB within the lifetime configured in this command.

Examples

# Set the maximum lifetime for RIP routes and labels in the RIB to 60 seconds.
