Configuring the Filtering of the Received Routing Information
Networking Requirements
Switch A communicates with Switch B, running OSPF protocol.
■
Import three static routes by enabling the OSPF protocol on Switch A.
■
The route filtering rules can be configured on Switch B to make the received three
■
static routes partially visible and partially shielded. This 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.

Configuration procedure
1 Configure Switch A:
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
b 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
