Description | Let's configure the OSPF protocol according to the scheme. Step 1: start OSPF. Step 2: configure the router IDs. The identifiers will be equal to the IP addresses assigned to the loopback interface. Step 3: define the interfaces where OSPF should be started. All the interfaces are connected to the backbone area according to the scheme. Step 4: define the area types: area 3 - NSSA, area 4 - Stub. Note that the area type must be configured on all the routers connected to that area, otherwise they will not establish neighboring relations. Step 5: perform the redistribution of the directly connected networks on the BS1 router and pf of the static routes on the CPE3 router. Step 6: configure passive interfaces. | |||||||

Description | Let's analyze the LSDB. Unlike in the case of the scheme with one area, in this example the LSA set of LSAs for each area will be different. Area 0:
Area 3:
Area 4:

Description | The routing tables of the wireless devices , contain entries about each subnet shown in the scheme. This means that the devices have successfully exchanged the routing information and added it to the FIB. The main difference between the routing tables of the devices are the routes to the external networks: on some routers there is a direct route to the network, and on others a default route. Note: the addresses of the loopback interfaces do not depend on the link state, therefore they can be used to manage the devices in redundant networks. | |||||||
