Configuring VRRP

When multiple routers are available to forward traffic, the Virtual Router Redundancy Protocol (VRRP) is used to provide fast automatic fail-over for hosts when the default gateway fails. This eliminates the single point of failure inherent in the static default routed environment. A Master VRRP router controls the IP addresses associated with the virtual router and forwards packets sent to these IP addresses. The backup router is always on standby. If the Master router fails, the backup router takes over. Multiple virtual routers can be created per interface. VRRP can be enabled or disabled globally or on an interface basis.
