-4 103.103.103.3 --> Source
--------------------------------------------------------------
----
You can issue the mtrace command
specifying the source multicast tree and
multicast group without specifying the
destination. Mtrace traces the complete path
traversing through the multicast group to
reach the source. The output displays the
destination and the rst hop (-1) as 0 to
indicate any PIM enabled interface on the
node.

You invoke a weak mtrace request by
specifying only the source without specifying
the mulicast tree or multicast group
information for the source. Mtrace traces a
path towards the source by using the RPF
neighbor at each node.
