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
