Hello everyone. I have a 7613 / Sup720 router that has at least 30 multicast connections successfully streaming data via pim sparse-mode across different interfaces toclients. It's a cookie cutter configuration for each client basically.
However, on this particular client once PIM is enabled on his interface I can only see him as PIM neighbor and if he tries to make a connection I don't even see a (*,G). I thought that maybe it's an ACL problem on his side so I added and igmp static statement on his interface to just forward the packets...I checked the mroute table for the feed - and all I saw was the other 15 clients currently on it subscribing. I then replaced the static statement with a join-group statement thinking it may jump start the connection...still nothing in my mroute table. I switched to dense-mode and voila - I see a (*,G)...and a (S,G) too (since we run sparse-mode natively). However, once I switch back...I don't see any feeds being streamed....anything I could be looking for? The client is running sparse-mode and has the rp information for our stream...but I guess that doesn't still explain why I cannot see a join when I add a 'static-group command to their interface. Thanks in advance for the help

Hello Amin,
please provide
sh ip rpf source-ip-address
sh ip pim int typex/y
where typex/y is interface to troubled customer
sh run int typex/y
sh ip pim rp mapping
and what is the G group that the customer should join
Hope to help

Hello Amin,
this line may have an effect:
ip multicast boundary yt_mcast_out
see
http://www.cisco.com/en/US/docs/ios/ipmulti/command/reference/imc_03.html#wp1029655
what is the config of ACL yt_mcast_out ?
Hope to help
