If required, what password should be on the router in the MidEast branch office to allow a connection to be established with the Dubai router?
- No password is required
Explanation: In the diagram, DeepSouth is connected to Dubai’s S1/2 interface and is configured as follows:
IP address 192.168.0.5 255.255.255.252
Encapsulalation PPP ; Encapsulation for this interface is PPP
Check out the following Cisco Link:
Here is a snipit of an example:
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 the ppp authentication chap callin command is configured on Router 1. This is an example of a unidirectional authentication. In this setup, the ppp chap hostname alias-r1 command 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.
