RIP dynamic routing protocol configuration test

Background of the project

Planning and configuration interface IP address

[AR1-GigabitEthernet0/0/0]ip address 20.0.1.1 24
[AR1-GigabitEthernet0/0/1]ip address 10.0.1.1 24

AR2:

[AR2-GigabitEthernet0/0/0]ip address 20.0.1.2 24
[AR2-GigabitEthernet0/0/1]ip address 20.0.2.1 24

AR3

[AR3-GigabitEthernet0/0/0]ip address 20.0.2.2 24
