Hi all
I have noticed that unless you send your multicast ping output to a Loopback interface the PIM Registration does not occur and the test fails. I am guessing it is something to do with the PIM tunnel interfaces but I am really not sure. I also dont understand why the upstream neighbor wouldn't register the source if the traffic is received on a PIM enabled interface. (This is a Serial interface running Frame Relay and I have mapped the mcast group so the Multicast ping is received upstream)
Can anyone explain this in more detail or provide a any useful links on this?
Thanks
Nick
