Abstract: A method and system for identifying active and standby states of plural routers within a virtual router in a network is provided. The health of a virtual router represents whether the routers of the virtual router are configured for their appropriate active and standby states. For example, first information from a first and second router of a virtual router is obtained. The first information is used to determine the active and standby states within the virtual router. A topology of the network is produced identifying the active and standby states.
