Yes joseph,
This is what mentioned in IE Practice labs for Vol 4.1, but I am not
able to understand why and how it could happen by using following
commands
ip pim rp-address 150.1.2.2 1
access-list 1 permit 224.0.1.39
access-list 1 permit 224.0.1.40
Acc to these commands, 150.1.2.2 is the default RP for these 2 groups if
no other RP is reachable.
Could anyone else throw some light on this?
Regards,
Gops

Yes, You can.
You'll have to specify an RP manually to them though on each router
pariticipating in Auto-RP. Specially with NBMA-mode.
ip pim rp-address 150.1.2.2 1
access-list 1 permit 224.0.1.39
access-list 1 permit 224.0.1.40
150.1.2.2 would be an IP address reachable and I'd have it enabled with
ip pim sparse-mode "Though I am not sure of that".
Joseph.
