There's a problem with your AG multicast tunnel.  First, I had shut down 
your tunnel due to some problems here at Argonne and forgot to fix 
it.  Second, now I can't get to your router at all.  Here's what a 
traceroute says:

fire% traceroute 164.122.38.2
traceroute: Warning: Multiple interfaces found; using 140.221.9.181 @ hme0

Finally, it would be a great deal of help if you could run your IP 
Multicast Beacon on your AG node Linux box at all times.  That way we could 
debug and test connectivity independent of whether you have someone there 
at the time.
