Table 73. Mtrace Scenarios (continued)
Scenario Output
0 1.1.1.1 --> Destination
-1 * * * *
---------------------------------------------------------
---------
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 buffer 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 scenario, a
corresponding error message is displayed.
