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.
