Virtual Router Redundancy Protocol Commands
To configure VRRP, select an interface on one router in the group to serve
as the master virtual router. This physical interface is used as the virtual
address for the router group. Now set the same virtual address and a
priority on the backup routers, and configure an authentication string. You
can also enable the preempt feature which allows a router to take over as
the master router when it comes on line.
vrrp ip
Use this command to enable the Virtual Router Redundancy Protocol
(VRRP) on an interface and specify the IP address of the virtual router.
