You will need to join group 224.10.10.10 and 224.20.20.20 on either the
ethernet of R2 or R5 to be able to see RP and join the group, if you are
using sparse dense mode I think the issue maybe that the shared tree is
being pruned back at R3
Thanks

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:
