Usage Guidelines If you omit all the optional arguments and keywords, the show ip mroute command displays all the
entries in the IP multicast routing table.
The show ip mroute active kbps command displays all the 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"
refers to 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 (through Reverse Path Forwarding (RPF).
