PPP Encapsulation Configuration

PPP Encapsulation: 

HDLC stands for High-Level Data Link Control. It is the default encapsulation for synchronous serial links on Cisco routers. We would only use the encapsulation hdlc command to return the link to its default state. HDLC is an open standard protocol, Cisco modified HDLC  as part of its implementation. It allows for multi protocol support before PPP is specified. So, We should only use HDLC between Cisco devices. If we are connecting to a non Cisco device, We will use synchronous PPP.
 Lab Steps:
1. Assigning IP address to both routers
2. Setting the PPP encapsulation
3. Setting the clocks on router 


Step- 1:

Router 1
Router1(config)#int serial 2/0
Router1(config-if)# ip address
Router1(config-if)# no shut

Router 2
Router2(config)# int serial 2/0
Router2(config-if)# ip address
Router2(config-if)# no shut


Router1(config)#in se 2/0
Router1(config-if)#encapsulation ppp
Router1(config-if)# clock rate 64000

Router2(config)#in se 2/0
Router2(config-if)#encapsulation ppp
Router2(config-if)# clock rate 64000
