PPP encapsulation is used on the WAN connections, which is offered by the service providers through a leased line.

PPP (Point to Point Protocol) is an industry standard protocol. As a result, this protocol is supported by many vendors that produce the networking devices.

PPP has many features like data compression, authentication and multi-link that make it very popular among the companies.

In this lab, we will configure PPP protocols on the routers. PPP should be enabled on both the routers to work, as the routers are required to use the same protocol to establish a connection. Also, we will set up clocking on the router 0 that is connected with DCE side of the cable.

1. Assign IP address to both routers
2. Set PPP encapsulation
3. Set clocking

Lab Configuration

Task 1

Router 0

Router(config)#int se 2/0

Router(config-if)# no shut

Router 1

Router(config)# int se 2/0

Router(config-if)# ip address 192.168.1.2 255.255.255.0

Router(config-if)# no shut

Task 2

On both routers

Router(config)#in se 2/0

Router(config-if)#encapsulation ppp
