show ip mroute

Displays the IPv4 multicast routing table.

show ip mroute [ group group [ source source ] ] [ dense | sparse | count | summary ]

When used with no option, this command displays information for the complete IPv4 multicast routing table.

group group
Shows IPv4 multicast routes for the specified multicast group. The format is an IPv4 multicast address.
source source
Used in source-specific multicast. Shows multicast routes for the specified IPv4 multicast source. The format is an IPv4 multicast address.
dense
Shows dense-mode IPv4 multicast routes.
sparse
Shows sparse-mode IPv4 multicast routes.
count
Shows IPv4 multicast-route and packet-count information.
summary
Shows abbreviated IPv4 multicast route information.

Operational mode

Use this command to display the IPv4 multicast routing table.

The following example shows how to display an IPv4 multicast routing table.

vyatta@vyatta:~$ show ip mroute
