3Com Switch 8800 Configuration Guide Chapter 22 IP Routing Policy Configuration22-1122.4 Typical IP Routing Policy Configuration Example22.4.1 Configuring to Filter the Received Routing InformationI. Network requirementsz Switch A communicates with Switch B, running OSPF protocol. The router ID ofSwitch A is 1.1.1.1, and that of Switch B is 2.2.2.2.z Import three static routes through enabling the OSPF protocol on the Switch A.z The route filtering rules can be configured on Switch B to make the received threestatic routes partially visible and partially shielded. It means that routes in thenetwork segments 20.0.0.0 and 40.0.0.0 are visible while those in the networksegment 30.0.0.0 are shielded.II.
