VRRP group

A VRRP group consists of a cluster of interfaces or virtual interfaces that provide redundancy for a primary, or 'master' interface in the group.

Each interface in the group is typically on a separate router. The VRRP process on each system manages redundancy.

Each VRRP group has a unique numeric identifier. You must assign the same VRRP group identifier and virtual address to all interfaces in the group; otherwise, they cannot provide redundancy for each other.

You can assign up to 20 virtual IP addresses to a VRRP group. Interfaces that are being mapped to a virtual address cannot have the same address as the virtual address.

Note:

VRRP version 3 provides owner mode. This does allow interfaces to have the same address as the virtual address.

The addresses of the interfaces that participate in the VRRP group must be on the same subnet for the protocol to work. It is common, but not a requirement, for the virtual IP address to be on this subnet.

An interface can support multiple VRRP groups.
