I am not familiar with mtest, but you might want to use the appliacations:

mrinfo tells the information and status of  the tunnels and physical interfaces.
to use (as root):	mrinfo YOUR.MBONE.ROUTER.DOMAIN
and it responds somthing like:

bash# mrinfo localhost
127.0.0.1 (localhost) [version 3.8,prune,genid,mtrace]:
  134.129.125.191 -> 0.0.0.0 (local) [1/1/querier/leaf]
  134.129.48.1 -> 0.0.0.0 (local) [1/1/querier/leaf]
  134.129.125.191 -> 111.11.111.11 (our.provider.net) [1/64/tunnel]
  134.129.125.191 -> 128.128.128.128 (made-up-host.somewher.com) [1/48/down]

notice we have two interfaces on the mrouter machine and it serves both
interfaces seperately. the tunnel to "made-up-host.somewher.com" is not
connected, but the other tunnel to "our.provider.net" is connected.
if your tunnel to your provider is working, then query the provider to see
if the problem is upstream to you.

you can look in /var/log/messages to see if there were any reason your mrouted
did not start. you also start mrouted with a debug option greater than 0 to get
more information about your tunnel.

I also watch the network to see if multicast session broadcast are making it
from the mrouted to the net by running as root:  tcpdump net 224

The application map-mbone is a nice application to run, but it won't tell
why your local tunnel is not working.
