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
tunnel is defined using IP addresses, a source IP address and a desti-
nation IP address.
Adding a tunnel A DVMRP tunnel must be set up in both switches over the tunnel.
