SROS Command Line Interface Reference Guide Demand Interface Configuration Command Set
Configuring CHAP Example 4: Using the ppp chap password command as an alternate solution.
On the local router (hostname Local):
Local(config-demand 1)#ppp authentication chap
Local(config-demand 1)#username Peer password different
On the peer (hostname Peer):
Peer(config-demand 1)#username Local password same
Peer(config-demand 1)#ppp chap password different
Here the local router challenges with hostname "Local." The peer verifies the name in the username
database, but instead of sending the password "same" in the response, it uses the one in the ppp chap
password command. The local router then verifies that user "Peer" with password "different" is valid and
sends a "success."
