------------------------------------------------------------------
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
show ip mroute
View the multicast routing table.
Syntax
show ip mroute [static | group-address [source-address] | count | snooping
[vlan vlan-id] [group-address [source-address]] | summary | vlt [group-address
[source-address] | count]
Parameters
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.
