DVMRP Tunnels
Introduction This routing switch supports the Distance Vector Multicast Routing
Protocol (DVMRP). This enables IP multicast packets to be encapsu-
lated in an IP header, and sent through a tunnel between two specific
switches on a network that does not support DVMRP routing. The

nation IP address.
