Dear Friends,
Need Confirmation About CHAP Authentication in PPP Encapsulation.
I have a lab topology R1 -----serial----------R2
R1 have PPP encapsulation through R2
Have A Task to do :
1. Configure R1 to challenge Chap Authentication to R2
2. R2 should respond with password CISCO
3. no username command at R2
The solution provided :
R1.
username R2 password CISCO
interface serial
encapsulation PPP
clockrate 64000
ppp authentication CHAP
R2.
interface serial
encapsulation PPP
ppp chap password CISCO
I tried the solution but it cannot make my line protocol serial goes up.
My understanding about PPP Authentication CHAP so far is that we need to
authenticate the router both direction. So I Think there is no way that we
can get this authentication works without 'username command' on R2.
Cause R1 need to authenticate also to R2 right ?
But I also try this solution of mine but it doesn't work either :) Make me
frustated.
Can anyone help ?
Thanks in advance guys
Regards
