Router loopback port experiment

1. To configure IP

2. Realize the interconnection between the three devices , By enabling dynamic routing RIP

With R2 For example :

Router(config)#router rip   // Enable RIP agreement

Router(config-router)#network 192.168.12.0    // Declare 192.168.12.0 Network segment

Router(config-router)#network 192.168.23.0    // Declare 192.168.23.0 Network segment

3. Add loopback port on three equipment

With R1 For example ：

Router(config)#interface loopback 0

Router(config-if)#ip add 1.1.1.1 255.255.255.0

4. Add the route to the loopback port to the route table through static route

With R1 For example :

ip route 2.2.2.0 255.255.255.0 192.168.12.1

With R2 For example :

Router(config)#ip route 1.1.1.0 255.255.255.0 192.168.12.1

Router(config)#ip route 3.3.3.0 255.255.255.0 192.168.23.2

The whole network interworking between each loopback port can be realized
