Hope some one can shed some light on this...
I have a SUN running mrouted 3.8 and having a tunnel set up to a CISCO
2500 series with IOS 11.2.
It seems all work fine except that mrouted always having waring message
putting out every couple of seconds.
Here is the sample waring message from /var/message.

During 13:43 the cisco multicast routing table show about 10739 routes
which is too high.
Can somebody explain how the duplicate prune means and what is the
impact here. If the
group really got pruned at all.
Thanks
