5-7IP Route Policy Configuration ExampleConfiguring to Filter Received Routing InformationNetwork requirementsSwitch A communicates with Switch B. OSPF protocol is enabled on both switches. The router ID ofSwitch A is 1.1.1.1 and that of Switch B is 2.2.2.2.Configure three static routes and enable OSPF on Switch A.By configuring route filtering rules on Switch A make the three received static routes partially visible andpartially shielded: the routes of network segments 20.0.0.0 and 40.0.0.0 are visible, and the route ofnetwork segment 30.0.0.0 is shielded.Network diagramFigure 5-1 Filter received routing informationArea 0Vlan-Int 200Router ID:1.1.1.1Switch A Switch BRouter ID: 2.2.2.212.0.0.1/8Static 20.0.0.0/830.0.0.0/840.0.0.0/810.0.0.1/8 10.0.0.2/8Vlan-Int 100Configuration procedurez Configure Switch A:# Configure the IP addresses of the interfaces. system-view[SwitchA] interface vlan-interface 100[SwitchA-Vlan-interface100] ip address 10.0.0.1 255.0.0.0[SwitchA-Vlan-interface100] quit[SwitchA] interface vlan-interface 200[SwitchA-Vlan-interface200] ip address 12.0.0.1 255.0.0.0[SwitchA-Vlan-interface200] quit# Configure three static routes.[SwitchA] ip route-static 20.0.0.0 255.0.0.0 12.0.0.2[SwitchA] ip route-static 30.0.0.0 255.0.0.0 12.0.0.2[SwitchA] ip route-static 40.0.0.0 255.0.0.0 12.0.0.2# Enable the OSPF protocol and specify the ID of the area to which the interface 10.0.0.1 belongs. system-view[SwitchA] router id 1.1.1.1
