Basic VRRP Topology

A Basic VRRP Topology shows a basic VRRP topology with a single virtual router. Routers R1 and R2 are both configured with one virtual router (VRID 1). Router R1 serves as the master and Router R2 serves as the backup. The hosts are configured to use 172.111.1.1/16 as the default route.

If Router R1 should become unavailable, Router R2 would take over virtual router VRID 1 and its associated IP addresses. Packets sent to 172.111.1.1/16 would go to Router R2. When Router R1 comes up again, it would take over as master, and Router R2 would revert to backup.
