RGMP: Router Port Group Management Protocol

The Router Port Group Management Protocol (RGMP) is defined by Cisco Systems to address the limitations of Internet Group Management Protocol (IGMP) in its Snooping mechanism. RGMP is used between multicast routers and switches to restrict multicast packet forwarding in switches to those routers where the packets may be needed. RGMP is designed for backbone switched networks where multiple, high speed routers are interconnected.
