Command Reference Guide Demand Interface Configuration Command Set

Configuring CHAP Example 4: Using the ppp chap password command as an alternate solut ion.

On the local router (hostn ame 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 "Lo ca l." 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."
