show ip mroute
show ip mroute
To display IP multicast routing table information, use the show ip mroute command.
show ip mroute [interface_type slot/port | host_name | host_address [source] | active [kbps |
interface_type num] | count | pruned | static | summary]
Syntax Description
Defaults This command has no default settings.
Command Modes Privileged EXEC mode
Command History
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).
interface_type
slot/port
(Optional) Interface type and number of the slot and port; valid values for
interface type are fastethernet, gigabitethernet, tengigabitethernet, null, and

host_name (Optional) Name or IP address as defined in the DNS hosts table.
host_address
source
(Optional) IP address or name of a multicast source.
active (Optional) Displays the rate that active sources are sending to multicast groups.

values are from 1 to 4294967295 kbps.
count (Optional) Displays the route and packet count information.
pruned (Optional) Displays the pruned routes.
