Scenario 3: The function of OSPF importing the routers of other OSPF processes

As shown in the following graph, a switch running the OSPF routing protocol connects two networks: network

A and network B. Because of some reason, it is required that network A should be able to learn the routers of

network B, but network B should not be able to learn the routers of network A. According to that, two OSPF

processes can be started respectively on interface vlan 1 and interface vlan 2. the OSPF process which

interface vlan 1 belongs to is configured to import the routers of the OSPF process which interface vlan 2

belongs to, while the OSPF process which interface vlan 2 belongs to should not be configured to import the

routers of the OSPF process which interface vlan 1 belongs to.

We can configure as follows:
