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.
  1. Enter global configuration mode.
    device# configure terminal
  2. Enter the ip hitless-route-purge-timer command, specifying a value, to set the IPv4 hitless purge timer for the default VRF.
    device(config)# ip hitless-route-purge-timer 60

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
