DVMRP implements its own unicast routing protocol (similar to RIP) to determine which interface leads back to the source of the data stream. The path that the multicast traffic follows may not be the same as the path that the unicast traffic follows. |
DVMRP has been used to build the MBONE by building tunnels between DVMRP-capable machines. |
DVMRP is state of the art today. |
