Virtual Router Backup
A new virtual router master is selected from the set of VRRP routers available to assume
forwarding responsibility for a virtual router should the current master fail.
Owner and Non-Owner VRRP
The owner controls the IP address of the virtual router and is responsible for forwarding packets
sent to this IP address. The owner assumes the role of the master virtual router. Only one virtual
router in the domain can be configured as owner. All other virtual router instances participating in
this message domain must have the same VRID configured.
The most important parameter to be defined on a non-owner virtual router instance is the priority.
The priority defines a virtual router’s selection order in the master election process. The priority
value and the preempt mode determine the virtual router with the highest priority to become the
master virtual router.
The base priority is used to derive the in-use priority of the virtual router instance as modified by
any optional VRRP priority control policy. VRRP priority control policies can be used to either
override or adjust the base priority value depending on events or conditions within the chassis.
For information about non-owner access parameters, refer to VRRP Non-Owner Accessibility on
