Distance Vector Multicast Routing Protocol

From Wikipedia, the free encyclopedia

The Distance Vector Multicast Routing Protocol (DVMRP) is used to share information between routers to transport IP Multicast packets among networks.

It is based on the RIP protocol to forward packets: the router generates a routing table with the multicast group that it has knowledge with its corresponding distance (number of devices -routers- in the middle to reach it). When a Multicast packet is received by a router, it is forwarded by router's interfaces specified in the routing table.

The DVMRP protocol uses IGMP messages to exchange information with other routers.
