Hands-on Labs
I
n this section, you will configure Cisco routers in four different WAN
labs using the figure supplied in each lab. These labs are included for use with
real Cisco routers. If you are using the Sybex Router Fundamentals Simulator
provided on this book's companion CD, please use the hands-on labs found
within that software program.
Lab 10.1: Configuring PPP Encapsulation and Authentication
Lab 10.2: Configuring and Monitoring HDLC
Lab 10.3: Configuring Frame Relay and Subinterfaces
Lab 10.4: Configuring ISDN and BRI Interfaces
Hands-on Lab 10.1: 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 Figure 10.8.
