In this section, you will configure Cisco routers in three different WAN labs using the figure supplied in each lab. (These labs are included for use with real Cisco routers but worked perfectly with Cisco’s Packet Tracer program.)
Lab 16.1: Configuring PPP Encapsulation and Authentication
Lab 16.2: Configuring and Monitoring HDLC
Lab 16.3: Configuring Frame Relay and Subinterfaces
Hands-on Lab 16.1: Configuring PPP Encapsulation and Authentication
By default, Cisco routers use High-Level Data-Link Control (HDLC) as a point-to-point encapsulation method on serial links. If you are connecting to non-Cisco equipment, then you can use the PPP encapsulation method to communicate.
The lab you will configure is shown in the following ...
