Forgive me.... Archives down...
In playing with the PPP authentication I have a couple questions hopefully
someone can answer. Looking for clarity as always. In reviewing the below,
please keep in mind that my configs other than the authentication work fine.
If I put in PPP authentication chap on both sids I connect and can ping side
to side..
1. If I configure no ppp authentication on either side, there is no
challenge/response by either party. Link goes up/up. Can not ping. Do I
HAVE to have some sort of authentication in order to establish communication?
2. Continuing question 1, is it mandatory to have username and password for
PPP negotiation/authentication? In other words if I have no user
names/passwords and configure no ppp authentication on either side I connect
and go up/up but can not ping. Debug ppp negotion looks fine and of course
there is no challenge so I figured I should be able to communicate accross
the link but I guess not. Apparently this is the way it is supposed to work.
Can anyone confirm?
3. When I configure PPP authentication only on the CALLED side, it does
indeed challenge and authenticates. I can ping no problem. If I do it
the other way and put PPP authentication only on the CALLING side, I connect
and there is a successfull challenge/response, but I can not ping. Why
does it work when the called side initiates the challenge but not the other
way around? Is this the way it is supposed to work?
Thanks,
David
