Each router in a network is configured for generating router advertisement messages according to a flooding distance vector routing protocol. Each router advertisement message output according to the flooding distance vector routing protocol includes reachability information for at least one destination, and an originating router identifier indicating a router having originated the reachability information. If any router receiving the router advertisement message detects a match between the originating router identifier and the corresponding assigned router identifier, the received router advertisement message is disregarded during calculation of the best paths from the network. If the originating router identifier identifies another router, the router floods the received router advertisement message to other ports, and output its own router advertisement message based on the received router advertisement message and that specifies the originating router identifier from the received router advertisement message.
