5.1.8 VRRP
This page is used to configure Virtual Router Redundancy Protocol.
VRRP provides for automatic assignment of available IP routers to participating hosts. This
increases the availability and reliability of routing paths via automatic default gateway selections
on an IP subnetwork. The protocol does this by creation of virtual routers, which are an abstract
representation of multiple routers (i.e., master and backup routers, acting as a group). The default
gateway of a participating host is assigned to the virtual router instead of a physical router. If the
physical router that is routing packets on behalf of the virtual router fails, another physical router is
selected to automatically replace it. See IETF
There are several options for each VRRP Group and each VLAN:
Label
