-4 103.103.103.3 --> Source
------------------------------------------------------------------
The mtrace command traverses the path of the response data block in the reverse direction of
the multicast data traffic. The mtrace command traverses the reverse path to the source from the
destination. As a result, the tabular output of the mtrace command displays the destination details in the
first row, followed by the RPF router details along the path in the consequent rows, and finally the source
details in the last row. The tabular output contains the following columns:
● Hop — a hop number(counted negatively to indicate reverse-path)
● OIF IP — outgoing interface address
● Proto — multicast routing protocol
● Forwarding code — error code as present in the response blocks
● Source Network/Mask — source mask

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.
