Using an ACL to Filter OSPF Routes

Using an ACL to Filter OSPF Routes

An ACL can be applied to various dynamic routing protocols to filter advertised and received routes.

In Figure 5-9, the network runs the Open Shortest Path First (OSPF) protocol. RouterA receives routes from the Internet and advertises the routes to the OSPF network. The OSPF network is allowed to access only three network segments:,, and The network connected to RouterC is allowed to access only the network segment

To meet the preceding requirements, an ACL and a routing policy are configured on RouterA. This routing policy permits RouterA to advertise only the routes on network segments,, and to RouterB, so that the OSPF network can access only these three network segments. An ACL and a routing policy are also configured on RouterC. The routing policy permits RouterC to receive only the route, so that the network connected to RouterC can access only the network segment
