Looking for Definition of DVMRP- Distance Vector Multicast Routing Protocol or what DVMRP stands for?
DVMRP is the original protocol for multicast IP routing. It was planned to operate both on multicast LANs (similar to Ethernet) and non-multi-cast routers. For routers that cannot be multicast, the IP multicast packets are ‘tunned’ as unicast packets via the routers. DVMRP has an impact on efficiency when it replicates packets but offers an intermediate option for multicast IP routing over the Internet where router vendors want to support native multicast IP routing.
DVMRP defaults to make all multi-casts interfaces when configured.
