Abstract
A method for application broadcast forwarding for routers running redundancy protocols in a network is provided. The network includes a first router running at least one program instance of a redundancy protocol at one interface, and a second router running at least one program instance of the redundancy protocol at one interface. A relay agent is enabled on both the first and second routers. The method includes, for each router, determining at least one preference ID for the router, determining a broadcast ID of each incoming broadcast packet, matching the broadcast ID of the incoming broadcast packet with the at least one preference ID of the router, and relaying the incoming broadcast packet from a first network domain to a second network domain if the broadcast ID of the incoming broadcast packet matches one preference ID of the router.
