The following 2 refences will give you some guidance on how to do that:

https://supportforums.cisco.com/docs/DOC-22848

‎

and for RPL:

You will need to use RPL to define your prefix sets (as opposed to prefix lists you have in IOS)

to filter inbound and outbound route updates.

You also use the RPL to modify BGP attributes.

The neighbor and network statements (need to be under the address family ipv4 unicast) are pretty much the same as in IOS.
