Nate,
Could you clarify your question some more? If you are asking if
you can filter prefixes based on address in an inbound route-map, then
yes you can. You can not match on address directly, but must instead
must match an access-list or prefix-list.
The following syntax accepts only the prefix 1.2.3.0/24 from the
BGP neighbor 10.20.30.40.
Ip prefix-list X permit 1.2.3.0/24
!
route-map Y permit 10
match ip address prefix-list X
!
router bgp 10
neighbor 10.20.30.40 route-map Y in
Is this what you are asking?
