You can issue the mtrace command
by providing the source and multicast
information. However, if the multicast
group is a shared group (*,G), then
mtrace traces the path of the shared tree
until it reaches the RP. The source mask
field reflects the shared tree that is being
used to trace the path. The shared tree
is used even in case where the source
provided is not valid.
R1>mtrace 3.3.3.3 1.1.1.1 226.0.0.3
Type Ctrl-C to abort.
Querying reverse path for source 3.3.3.3 to destination
1.1.1.1 via group 226.0.0.3
From source (?) to destination (?)
---------------------------------------------------------
--------
|Hop| OIF IP |Proto| Forwarding Code |Source

---------------------------------------------------------
--------
0 1.1.1.1 --> Destination
-1 1.1.1.1 PIM - shared
tree
-2 12.12.12.1 PIM Reached RP/Core shared
tree
---------------------------------------------------------
---------
When you issue the mtrace command
with the source and multicast group
information, if a multicast route is not
present on a particular node, then the
NO ROUTE error code is displayed on
the node. In this scenario, the Source
Network/Mask column for that particular
node displays the the value as default.
R1>mtrace 6.6.6.6 4.4.4.5 234.1.1.1
Type Ctrl-C to abort.
Querying reverse path for source 6.6.6.6 to destination
4.4.4.5 via group 234.1.1.1
From source (?) to destination (?)
