I am using autorp how can i preven any new rp with higher ip address from taking over, rp-announce-filter requires me to specify the rp specifically which should be denied, what if I do not know what the new rp is going to be?

I have this problem too.

You dont know which RP addresses you want to filter. But if you know which Ip addresses you can atleast accept as RP, you could use the following command :

Ferrari(config)#ip pim accept-rp auto-rp ?

<1-99> Access-list reference for group

<1300-1999> Access-list reference for group (expanded range)

WORD IP Named Standard Access list

So the device can only accept the IP addresses matching the ip access list and announced through auto-rp as the possible RP.
