We are filtering routes inbound using an OSPF setup. We are filtering the routes populating the routing table, we do not need to stop the routes entering the OSPF database.
We currently use standard numbered ACL's (1-99) linked to a route-map to achieve this. I am looking at other options in order to provide greater flexibility i.e. named ACL's, prefix-lists etc.
Can anybody provide any suggestions/recommendations as to the most flexible yet robust method?
I am running this on a 3750 with the Enhanced image.
