CHAP Password

[lifebook567]

"In PPP, the password configured on both routers must match" Is this statement correct? Or just match the other end hostname and password? Ex. RouterA has password of Cisco and RouterB has password of ABC. Can I configure RouterA to have "username RouterB password ABC" and configure RouterB to have "username RouterA password Cisco"?

Hello,

in addition to Edison's post, CHAP passwords, as opposed to PAP password, need to match on both sides of the link, the reason being that when one device sends a CHAP challenge, the other device will respond with a hash based partially on the matching password. Try and debug your PPP connection with ' debug ppp negotiation', both with matching and non-matching passwords, to see the difference in the negotiation outcome...
