mrinfo mbone-gw

35.8.2.15 (mbone-gw.cl.msu.edu) [version 3.8,prune,genid,mtrace]:
  35.8.2.15 -> 0.0.0.0 (local) [1/1/querier/leaf]
  35.8.2.15 -> 198.108.2.20 (mbone.merit.edu) [1/32/tunnel]
  35.8.2.15 -> 35.8.48.77 (pads1.pa.msu.edu) [1/1/tunnel/down/leaf]
  35.8.2.15 -> 35.8.98.9 (legato.cl.msu.edu) [1/1/tunnel/leaf]
  35.8.2.15 -> 35.9.3.2 (lewtest-gw-s9-3.msu.edu) [1/1/tunnel]

That looks good (not that I know what Im looking for :) and tcpdump shows
traffic on net 224... What now?  SDR still shows nothing..
