VRRP: Increasing Reliability and Failover with the Virtual Router Redundance Protocol

2.5. Ownership

We have already described different aspects of the mechanism VRRP defines for protecting interfaces, enabling a router to act as a default first hop router. In all the configurations we have discussed so far, the IP address protected by the virtual router was the real IP address of one of the participant VRRP routers. Take the configuration depicted in Figure 2-6. In this configuration the IP address protected by the virtual router V1 is the IP address of the router R1. We refer to such routers, the real IP address(es) of which is associated with the virtual router, as owner. In Figure 2-6, by definition, R1 is not only the master but also an owner. For example, in Figure 2-6, the IP address IP(V1) protected by virtual router V1 ...
