Hi nisha,
I'm not a multicast expert. Cisco's recommendation when you run Auto-RP is
that you must be in sparse-dense-mode. Also dynamically learned RP are
preferred over static RP announcement. So I dont see the need for the ip pim
rp-address 10.10.125.5 (unless your scenario calls for it). If you will stick
to your config. (Sparse-mode). You will need something that allows auto-rp
packets across sparse-mode interface. After you do that. Do sh ip pim rp
mapping. Then after that you'll be okay (I think).
I'm not 100% sure about this but give it a try.
