Yes, it did same thing yesterday.
After I configured basic multicast configuration "sparse-mode,
auto-rp,mapping agent, and rp loopbacks and mapping agent loopbacks enabled
pim sparse mode, etc", I cannot ping any mullticast group. But, after I
enable sparse mode on loopbacks of other routers which I participate in
multicast, I can ping the group.
I don't know why? Any one can make clear?
Cheers,
Laurence
