View the multicast routing table.

Syntax
show ip mroute [vrf vrf-name] [static | group-address [source-address] | count | snooping [vlan vlan-id] [group-address [source-address]] | summary | vlt [group-address [source-address] | count]
Parameters
vrf vrf-name
(OPTIONAL) Enter the keyword vrf followed by the name of the VRF to configure this setting on that VRF.
NOTE: Applies to specific VRF if input is provided, else applies to Default VRF.
static
(OPTIONAL) Enter the keyword static to view static multicast routes.
group-address [source-address]
(OPTIONAL) Enter the multicast group-address to view only routes associated with that group. Enter the source-address to view routes with that group-address and source-address.
count
(OPTIONAL) Enter the keyword count to view the number of multicast routes and packets.
snooping [vlan vlan-id] [group-address [source-address]]

Enter the keyword snooping to display information on the multicast routes PIM-SM snooping discovers.

Enter a VLAN ID to limit the information displayed to the multicast routes PIM-SM snooping discovers on a specified VLAN. The VLAN ID range is from 1 to 4094.

Enter a multicast group address and, optionally, a source multicast address in dotted decimal format (A.B.C.D) to limit the information displayed to the multicast routes PIM-SM snooping discovers for a specified multicast group and source.

summary
(OPTIONAL) Enter the keyword summary to view a summary of all routes.
vlt
(OPTIONAL) Enter the keyword vlt to view multicast routes with a spanned incoming interface. Enter a multicast group address in dotted decimal format (A.B.C.D) to limit the information displayed to the multicast routes for a specified multicast group and optionally a source multicast address in dotted decimal format (A.B.C.D) to limit the information displayed for a specified multicast source. Enter the keyword count to display the total number of multicast routes with the spanned IIF.
