bgp: Route acquired by BGP

By default, the filtering of the received and advertised routes will not be 
performed.

After the above configuration, execute the display command in any view to 
display the running of the routing policy configuration, and to verify the effect of 
the configuration.

Switch A communicates with Switch B, running OSPF protocol. The router ID of 
Switch A is 1.1.1.1, and that of Switch B is 2.2.2.2.

Import three static routes through enabling the OSPF protocol on the Switch A.

The route filtering rules can be configured on Switch B to make the received three 
static routes partially visible and partially shielded. It means that routes in the 
network segments 20.0.0.0 and 40.0.0.0 are visible while those in the network 
segment 30.0.0.0 are shielded.
