Configuring IP Multicast 677
Distance Vector Multicast Routing Protocol
Distance Vector Multicast Routing Protocol (
DVMRP) exchanges probe packets with all its DVMRP
enabled routers, it establishes two way neighboring relationships, and it builds a neighbor table. It
exchanges report packets and creates a unicast topology table, with which it builds the multicast routing
table. This table is used to route the multicast packets. Since every DVMRP router uses the same unicast
routing protocol, routing loops are avoided.
The DVMRP menu page contains links to web pages that define and display DVMRP parameters and
data. To display this page, click IP Multicast > DVMRP in the tree view.
