IPv4 address family configuration
Usage Guidelines Under normal circumstances, you may not need to change the value of the route purge timer. If you
anticipate delay in learning the routes after switchover, you can configure a larger value for the route
purge timer.
Examples The following example shows how to set the IPv4 hitless purge timer on the default VRF:
Brocade(config)# ip hitless-route-purge-timer 500
The following example shows how to set the IPv4 purge timer on the non-default VRF:
Brocade(config)# vrf blue
Brocade(config-vrf-blue)# rd 10:10
Brocade(config-vrf-blue)# address-family ipv4
Brocade(config-vrf-blue-ipv4)# ip hitless-route-purge-timer 120
ipv6 hitless-route-purge-timer
Configures the maximum time before stale routes are purged from the routing information base (RIB)
after a switchover, failover, or OS upgrade. The no form of this command sets the purge timer time to
its default value.
Syntax ipv6 hitless-route-purge-timer seconds
no ipv6 hitless-route-purge-timer seconds
Parameters seconds
Maximum time, in seconds, before stale routes are purged. The valid range is from 2 to 600.
The default is 45 seconds.
Modes Global configuration
IPv6 address family configuration
Usage Guidelines Under normal circumstances, you may not need to change the value of the route purge timer. If you
anticipate delay in learning the routes after switchover, you can configure a larger value for the route
purge timer. IPv6 unicast routing must be enabled using the ipv6 unicast-routing command before
configuring the purge timer.
Examples The following example shows how to set IPv6 hitless purge timer on default VRF:
Brocade(config)# ipv6 hitless-route-purge-timer 500
The following example shows how to set IPv6 purge timer on a non-default VRF:
Brocade(config)# vrf blue
Brocade(config-vrf-blue)# rd 10:10
Brocade(config-vrf-blue)# address-family ipv6
Brocade(config-vrf-blue-ipv4)# ipv6 hitless-route-purge-timer 120
ipv6 hitless-route-purge-timer
