Hi Daniel,
1) I don't see "ip pim autorp listener" on R4 (BTW you don't need "no ip pim dm-fallback" when you are running sparse mode only, I believe)
2) Did you enable PIM on R1's loopback0?
3) how is your FR topology? full meshed? hub and spoke? who is the hub?
4) how is you routing over the frame relay cloud? can you do
show ip route of R1's loopback on R4 and R5?
5) "deb ip pim autorp" is very helpful at times to figure out problems
Sabrina

This time... I by-passed the R3 and just made the R1 router the MA as well
as the RP.
Thanks for helping.
