Setting the IPv4 Hitless Purge Timer
You can configure the timer to set the
duration for which the routes should be preserved after switchover. The following
task
configures the IPv4 hitless purge timer for the default VRF.
- Enter global configuration mode.
- Enter the
ip hitless-route-purge-timercommand, specifying a value, to set the IPv4 hitless purge timer for the default VRF.
The following example sets the IPv4 hitless purge timer on the default VRF to 60 seconds.
device(config)# ip hitless-route-purge-timer 60
The following example sets the IPv4 purge timer for a non-default VRF instance to 120 seconds.
device(config)# vrf blue device(config-vrf-blue)# rd 10:10 device(config-vrf-blue)# address-family ipv4 device(config-vrf-blue-ipv4)# ip hitless-route-purge-timer 120
