Lorenzo,
1) You don't need: "ip pim rp-address", when you use "sparse-dense-mode"
2) Why you are using "ip ospf network broadcast" (I believe it requires full
mesh), try "ip ospf network point-to-multipoint" instead
3) Don't use "ip pim nbma-mode" with "sparse-dense-mode", you don't need
that on FR point-to-point subinterfaces
3) Where is you ACL for group-list 5 on R2? It would help to see the full
config...
Please let the group know if you were able to resolve this issue and how...
Thanks,
Peter

I have the following topology:
R3(HUB)
| |
R5(spoke) R2 (sopoke)
I configured the multicast addresses on R2 Et0 224.10.10.10 and
224.20.20.20, I can reach them from R3 but I can4t from R5.
R2 is the RP(rendevouz point) and R3 is the MA (maping agent). I think that
I have the correct configuration but something is missing, does someone
knows what?????
Here are all the configs:
