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.
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.
