switching to expanded hop search, the
command displays an error message.

Timed out receiving responses
Perhaps no local router has a route for source, the receiver
is not
a member of the multicast group or the multicast ttl is too
low.
While traversing the path from source to
destination, if the mtrace packet exhausts
the maximum buer size of the packet, then
NO SPACE error is displayed in the output.
You can initiate a new mtrace query by
specifying the destination as the last IP
address from the output of the previous
trace query.

In a valid scenario, mtrace request packets
are expected to be received on the OIF of the
node. However, due to incorrect formation of
the multicast tree, the packet may be
received on a wrong interface. In such a
