Example
Configuring to Filter the
Received Routing
Information
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.

BGP
Display the address prefix list information
Network requirements
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.

# Configure the IP address of VLAN interface.
[Switch A] interface vlan-interface 100
[Switch A-Vlan-interface100] ip address 10.0.0.1 255.0.0.0
[Switch A] interface vlan-interface 200
[Switch A-Vlan-interface200] ip address 12.0.0.1 255.0.0.0
