DVMRP
DVMRP is an interior gateway protocol that is suitable for routing multicast traffic within an
autonomous system (AS). DVMRP should not be used between different autonomous
systems due to limitations with hop count and scalability.
Note: Only one multicast routing protocol can be operational on the switch
at any time. If you enable DVMRP, PIM must be disabled. Similarly, if
PIM is enabled, DVMRP must be disabled.
DVMRP exchanges probe packets with all its DVMRP-enabled routers, it establishes
two-way neighboring relationships, and it builds a neighbor table. DVMRP 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.
