I need a clarification on a fundamental concept of CHAP used in PPP links.
I am aware how CHAP works. It uses MD5 one way HASH Algorithm and inputs passwords as a element in the HASH. Thus passwords are not sent in clear text as PAP.
That means we are forced to use the same password in both the peer routers. For example,
username R2 password sairam
username R1 password sairam
Is it possible to use different passwords in both the routers as we do for PAP SENT-USERNAME command
Thanks in advance
I think that Sairam has asked about a mutual authentication of two PPP peers
If that's the case, then yes - password must be the same. I was thinking along the lines of one side authenticating the other (client - server design).
