I would configure

1. RP discovery agent on r1
2. RP itself can be on r1 or r4, either way it should work.

Subject: IP Multicast Sparse Mode with RP Question

When configuring IP Multicast with shared tree (Sparse
Mode) and RP where (which interface) should ip pim
sparse-dense-mode be configured and where (which
interface) should ip pim sparse-mode be configured?
Looking for best way to configure and reasoning behind
it.
Let's assume the below scenario:

4 routers Hub & Spoke
R1's the Hub router over NBMA
R2 & R3 directly connected to R1 over NBMA
R4 connected to R2 via ethernet link

Also assume one loopback interface configured
on R1, R2, R3 and to join Multicast group 225.5.5.5

Thanks.
