VRRP Configuration Overview

Configuring VRRP policies and configuring VRRP instances on interfaces and router interfaces is
optional. The basic owner and non-owner VRRP configurations on an IES or router interface must
specify the backup ip-address parameter.
VRRP helps eliminate the single point of failure in a routed environment by using virtual router IP
address shared between two or more routers connecting the common domain. VRRP provides
dynamic fail over of the forwarding responsibility if the master becomes unavailable.
The VRRP implementation allows one master per IP subnet. All other VRRP instances in the same
domain must be in backup mode.

VRRP policies must be configured before they can be applied to an interface or IES or
VPRN VRRP instance. VRRP policies are configured in the config>vrrp context.
The service customer account must be created prior to configuring an IES or VPRN VRRP
instance.
The interface address must be specified in the both the owner and non-owner IES, VPRN
or router interface instances.
