Basic Point to Point IPv4 addressing | Cisco Router

In this lab we will configure a simple point to point connection between two routers. 

We will use a 30-bit network to save address space.

R1

R1#config t
R1(config)#int gi0/0
R1(config-if)#ip address 192.168.10.1 255.255.255.252
R1(config-if)#no shutdown

R2

R2#config t
R2(config)#int gi0/0
R2(config-if)#ip address 192.168.10.2 255.255.255.252
R2(config-if)#no shutdown
