VRRPEndpoint is composed of a logical element defined per interface per VRRPGroup on a VRRP router. The VRRPGroup is created for each Virtual Router Identifier (VRID). VRRPEndpoints belonging to the same VRRPGroup (that is, having the same VRID) have a common Virtual IP and a Virtual MAC. The Virtual MAC is defined as xx-xx-xx-xx-xx-VRID. The VRRP enabled router having the highest priority is considered as the primary router and all other routers are considered as backup routers.
