Monitoring Critical Link State
To configure one or more ip addresses for a virtual router to monitor as critical link
states, use the ip vrrp verify-availability command in Interface Configuration mode,
as shown below. Use this command to configure a virtual router to monitor a link state
of another interface. If one or more IP addresses are configured for monitoring and all
monitored links are down, the virtual router is brought down automatically. The
master relinquishes responsibility by sending an advertisement 0. If at least one
monitored link comes back up, the associated virtual router is brought back up
automatically. Use the no ip vrrp verify-availability command to delete one or more
designated IP address from the virtual router.
MOT(config-if)#ip vrrp <num:1,255> verify-availability <address>
[...<ip-address>]
where:
number is the VRID; valid values are 1 to 255.
ip-address is the IP address this router monitors.
Example
In this example, the system is configured to monitor 198.112.190.11 and 20.20.20.11
for their availability. If both links are down, then VRRP 1 is brought down
automatically.
