13.1.3.4 show ip mroute
Use this command to display the multicast forwarding cache table. Since the DVMRP routing table
is not aware of group membership, the DVMRP process builds a forwarding cache table based on
a combination of information. This information includes items from the multicast routing table,
such at the source network/mask and upstream neighbors. Other items used to build the forwarding
cache table are source groups, received pruned neighbors and VLANs, upstream and downstream
VLANs, and other information, The forwarding cache table represents the local router’s
understanding of the shortest path source-based delivery tree for each (source, group) pair. Basically
it is the source’s RPM (Reverse-Path Multicast) for that group.
