OSPF multi-area configuration

ABR:area border router, area border router-functions to interwork between different areas;-defines routers that connect both backbone and non-backbone areas; why does OSPF introduce / partition areas? After dividing the area, you can bring the following benefits: 1. Save the system resources of each device in the area (after the large area is divided, the database content in the small area becomes less) (all routers in the same area The database is exactly the same) 2. Enhance the stability of the OSPF network (the adverse effects caused by an unstable link, only in the same area) (spread in, will not affect other areas)

Experimental steps and ideas:

one。 Configure network segments between different routers

1. Configure ip for AR1

Systen-view enters system mode

Rename syname R1

Interface g0Accord 0 enters the interface

Ip address 192.168.1.1 255.255.255.0 with ip

two。 Configure ip for AR2

Systen-view enters system mode

Syname R2 rename

Interface g0Accord 1 enters the interface

Ip address 192.168.1.2 255.255.255.0 with ip

Interface g0Accord 0 enters the interface

Ip address 192.168.2.1 255.255.255.0 with ip

3. Configure ip for AR3

Systen-view enters system mode

Rename syname R3

Interface g0Accord 1 enters the interface

Ip address 192.168.2.2 255.255.255.0 with ip

Interface g0Accord 0 enters the interface

Ip address 192.168.3.1 255.255.255.0 with ip

4. Configure ip for AR4

Systen-view enters system mode

Rename syname R4

Interface g0Accord 0 enters the interface

Ip address 192.168.3.2 255.255.255.0 with ip

Interface g0Accord 1 enters the interface

Ip address 192.168.4.1 255.255.255.0 with ip

5. Configure ip for AR5

Systen-view enters system mode

Syname R5 rename

Interface g0Accord 0 enters the interface

Ip address 192.168.4.2 255.255.255.0 with ip

Interface g0Accord 1 enters the interface

Ip address 192.168.5.1 255.255.255.0 with ip

6. Configure ip for AR6

Systen-view enters system mode

Syname R6 rename

Interface g0Accord 0 enters the interface

Ip address 192.168.6.2 255.255.255.0 with ip II. Create a virtual port (loopback port)

1. On AR1

Enter the virtual port to configure ip. Prevent line interruption from playing the role of remote connection

Interface loopback

Ip address 192.168.10.1 255.255.255.0

two。 On AR2

Enter the virtual port to configure ip. Prevent line interruption from playing the role of remote connection

Interface loopback

Ip address 192.168.20.1 255.255.255.0

3. On AR3

Enter the virtual port to configure ip. Prevent line interruption from playing the role of remote connection

Interface loopback

Ip address 192.168.30.1 255.255.255.0

4. On AR4

Enter the virtual port to configure ip. Prevent line interruption from playing the role of remote connection

Interface loopback

Ip address 192.168.40.1 255.255.255.0

5. On AR5

Enter the virtual port to configure ip. Prevent line interruption from playing the role of remote connection

Interface loopback

Ip address 192.168.50.1 255.255.255.0

6. On AR6

Enter the virtual port to configure ip. Prevent line interruption from playing the role of remote connection

Interface loopback

Ip address 192.168.60.1 255.255.255.0

three。 Create neighbor tabl

1. Create a neighbor table in AR1

Ospf {1} can be written or not written in parentheses. The default is 1.

Area 0 creates area 0, with numbers representing different areas

Network 192.168.1.1 .0.0.0.0 routing entries to learn

Network 192.168.10.1 0.0.0.0 0.0.0.0 stands for wildcard

two。 Build a neighbor table in AR2

Ospf {1} can be written or not written in parentheses. The default is 1.

Area 0 creates area 0, with numbers representing different areas

Network 192.168.1.2 0.0.0.0 routing entries to learn

Network 192.168.20.1 0.0.0.0 0.0.0.0 stands for wildcard

Area 24 should be created because AR2 belongs to the boundary as well as to area 24

Ospf

Area 24

Network 192.168.2.1 0.0.0.0

3. Create a neighbor table in AR3

Ospf {1} can be written or not written in parentheses. The default is 1.

Area 24 creates area 0, with numbers representing different areas

Network 192.168.3.1 0.0.0.0 routing entries to learn

Network 192.168.30.1 0.0.0.0 0.0.0.0 stands for wildcard

Network 192.168.2.2 0.0.0.0

4. Create a neighbor table in AR4

Ospf {1} can be written or not written in parentheses. The default is 1.

Area 24 creates area 0, with numbers representing different areas

Network 192.168.3.2 0.0.0.0 routing entries to learn

Network 192.168.40.1 0.0.0.0 0.0.0.0 stands for wildcard

Area 34 should be created because AR4 belongs to the boundary as well as to area 34

Ospf

Area 34

Network 192.168.4.1 0.0.0.0

5. Create a neighbor table in AR5

Ospf {1} can be written or not written in parentheses. The default is 1.

Area 34 creates area 0, with numbers representing different areas

Network 192.168.4.2 0.0.0.0 routing entries to learn

Network 192.168.50.1 0.0.0.0 0.0.0.0 stands for wildcard

Network 192.168.5.1 0.0.0.0

6. Create a neighbor table in AR6

Ospf {1} can be written or not written in parentheses. The default is 1.

Area 34 creates area 0, with numbers representing different areas

Network 192.168.5.2 0.0.0.0 routing entries to learn

Network 192.168.60.1 0.0.0.0 0.0.0.0 stands for wildcard
