RE: BSR question.......

Guys.........Just got it working.........I was running MPLS traffic
engineering tunnel between the three routers, and I was getting PRF failure on
the lo0 interfaces used for BSR. My routers were not getting any thing from
show ip pim rp mapping command and show ip igmp groups was not showing the
groups.

I configred the multicast static routes between my candidate RP and BSR
candidate and I'm able to ping the group address.

But thanks for your time and brain storming.

Here is the scenario R1 (candidate RP)--------> R2(using igmp joing
group)------------>R3 (bsr candidate)
