Be cautions when using BGP filters with ip addresses. Route maps cannot be
used to filter incoming updates based on an IP address. You will need to
use a BGP regular expression.

You could filter on the subnet length (I know, this is kind of like ip
address)
For instance, say you only wanted to accept routes with 24 bit subnet masks:
route-map infilter permit 10
match ip address 100
access-list 100 permit ip an host 255.255.255.0
