------------------------------------------------------------------
The mtrace command traverses the path of the response data block in the reverse direction of the multicast data
trac. 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 rst row, followed by the RPF router details
along the path in the consequent rows, and nally 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 specied 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 specied 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 specied multicast group and optionally
a source multicast address in dotted decimal format (A.B.C.D) to limit the information
displayed for a specied multicast source. Enter the keyword count to display the total
number of multicast routes with the spanned IIF.
