Traces the path from a source to a destination branch for a multicast
distribution tree. The trace follows the multicast path from the
destination to the source by passing an mtrace request packet to
each hop. The responses are unicast to the querying router by the
first hop router to the source. The mtrace command is helpful in
isolating multicast routing failures.
mtrace <source> [<destination>] [<group>]
