VRRP
Router Configuration Guide 373
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.
