Explanation:
In the diagram, DeepSouth is connected to Dubai’s S1/2 interface and is configured as follows:
Interface Serial1/2 IP address 192.168.0.5 255.255.255.252 Encapsulalation PPP ; Encapsulation for
this interface is PPP

Here is a snipit of an example:

Network Diagram
If Router 1 initiates a call to Router 2, Router 2 would challenge Router 1, but Router 1 would not
challenge Router 2. This occurs because theppp authentication chap callincommand is configured on
Router 1. This is an example of a unidirectional authentication. In this setup, theppp chap hostname
alias-r1command is configured on Router 1. Router 1 uses “alias-r1” as its hostname for CHAP
authentication instead of “r1.” The Router 2 dialer map name should match Router 1’s ppp chap
hostname; otherwise, two B channels are established, one for each direction.
