critical-ip
Use this command to set a critical IP address for VRRP routing. A critical IP address defines an
interface — in addition to the interface between hosts and a first-hop router — that will prevent the
master router from functioning properly if the interface were to fail. For example, an IP address of
an interface connecting a master router to a router configured for internet access would be
considered a critical IP address for VRRP routing. Up to four critical IP addresses can be configured
on the device.
critical-ip vlan vlan-id vrid ip-address
