ppp authentication

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
