22.4 Typical IP Routing Policy Configuration Example

22.4.1 Configuring to Filter the Received Routing Information

I. 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.

III. Configuration procedure
1) Configure Switch A:
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
Configure three static routes.
[Switch A] ip route-static 20.0.0.1 255.0.0.0 12.0.0.2
[Switch A] ip route-static 30.0.0.1 255.0.0.0 12.0.0.2
[Switch A] ip route-static 40.0.0.1 255.0.0.0 12.0.0.2
Enable the OSPF protocol and specifies the number of the area to which the interface
belongs.
[Switch A] router id 1.1.1.1
[Switch A] ospf
[Switch A-ospf-1] area 0
[Switch A-ospf-1-area-0.0.0.0] network 10.0.0.0 0.255.255.255
Import the static routes
