Usage Guidelines
If you omit all optional arguments and keywords, the show ip mroute command displays all entries in
the IP multicast routing table.
The show ip mroute active kbps command displays all sources sending at a rate greater than or equal
to kbps.
The multicast routing table is populated by creating source, group (S,G) entries from star, group (*,G)
entries. The star refers to all source addresses, the "S" refers to a single source address, and the "G" is
the destination multicast group address. In creating (S,G) entries, the software uses the best path to that
destination group found in the unicast routing table (that is, through Reverse Path Forwarding (RPF).
