Hi,
I am new to ppp, and have so much confusion about authentication. I have read many articles and threads, but my doubt is not cleared. Unfortunately, cisco documentation is not clear on many aspects.
R1 and R2 are connected back to back. I want to implement one-way authentication, R1 should challenge R2, but R2 should not. which one of the following two solutions is correct.
Sol1:
===
R1:
username R2 password cisco
int s1/1
ppp authentication chap callin
encap ppp
R2:
username R1 password cisco
int s1/1
ppp authentication chap
encap ppp
----------------------------------------------
Sol2:
R1:
username R2 password cisco
int s1/1
ppp authentication chap
encap ppp
R2:
int s1/1
encap ppp
ppp chap hostname R1
ppp chap password cisco
Kindly, let me know your suggestions on this.
Thanks,
Balajee
