Can you send the output of the following commands from each router?
Below each command is what I'm looking for with the command.
1) show ip route
Ensure full reachability. You can also ping to be 100% sure.
2) show ip pim neighbor
Verify the PIM neighbor relationship
3) show ip pim bsr-router
Verify the BSR information
4) show ip pim rp mapping
Verify the Group-to-RP mapping
5) show ip mroute count
Look for RPF failures
You should use a standard set of commands like these for basic
verification.

Subject: how can this not work!?!?
Hi Group,
i couldn't get this simple sparse mode multicast scenario working and am
pulling out my hair wondering why. I must've missed something simple
and have not been able to figure out why for couple of hours. Please
HELP!!
thanks
