I agree with you mate, just responded to Dan's comment ... "Can not be
done using auto-rp, you will need to use BSR."
Moreover, Jeff said no static-rp, so the only option will be one that
can push out the rp information to pim devices "automatically", Auto-rp
and BSR will usually fit the bill, but if you don't want to fiddle with
IP Address (when there is no higher address on R1 and you're not allowed
to configure a new one, and there is no restriction on using static-rp,
then obviously, you've got your alternative of combining static-rp with
auto-rp)
Many Thanks
Yemi Salau

I Think the only way to answer these requirements is to use pim
listener and make the pim source address of R1 bigger than R3 IP pim
source address.

Hello Dan,
Why can't Backup Rp be done with auto-rp? Without modifying the IP
Address of both RPs, I don't think BSR is the only way to go, also I
would be surprised if asked to configure BSR in a Cisco environment,
from the way things are going, Cisco is pushing the Auto-rp
implementation into the market more and more.
Remember when a PIM device receive 2 entries of RP information for same
group, it sticks (prefers) with the one from auto-rp over static-rp
information.
So in case you have R1 and R2 with loopback Ips of 1.1.1.1 and 2.2.2.2
respectively, if I want to make R1 the RP, I could do with a combination
of static and auto-rp without reconfiguring R1's IP
I would simply advertise R1 as RP for group X via auto-rp and advertise
R2 as RP for same group X via static-rp .... That way, pim routers will
always prefer R1 over R2 even though R1 has a lower IP address.... So if
the R1 is unreachable, they then switch to R2
Many Thanks
Yemi Salau

Hi Carlos,
Can not be done using auto-rp, you will need to use BSR.
Cheers,
Dan
