ONFIGURATION

By default, the filtering of the imported and distributed routes will not be 
performed.

After the above configuration, execute 

 command in all views to display 

the running of the routing policy configuration, and to verify the effect of the 
configuration.

■

Router A communicates with Router B, the link layer is encapsulated with the 
PPP protocol. OSPF protocol is enabled on both routers.

■

Configure the OSPF route process on Router A and import three static routes.

■

With the application of the route filtering rule configured in Router B, make the 
received three static routes partially visible and partially shielded---the routes of 
network segments 20.0.0.0 and 40.0.0.0 are visible, and the route of network 
segment 30.0.0.0 is shielded.
