Lorenzo,
I'm not a multicast expert, but let me try if I can help you...
Since R2 is a candidate RP, you need:
ip pim send-rp-announce int ser 0.1 scope 15
which makes the MA (mapping agent) aware of R2 as a candidate RP.
On R3, as an MA, you need:
ip pim send-rp-discovery int ser 0 scope 15
which sends out RP mappings to routers listening to 224.0.1.40.
On R5, since you are listening to 224.0.1.40, you don't need any
rp-address config:
[DELETE] ip pim rp-address 150.50.2.2
I hope this fixes your problem. Please let me know how it goes.
Cheers,
Geoffrey
