    How is this an OSPF problem? Do you have the clock rate configured? Paste your configs here or upload your packet tracer file.
    If at first you do succeed, try something harder.

    The protocol you are having issues with is PPP. Try issuing this debug command: debug ppp authentication. You are missing something crucial.

    Hint: What do you need for authentication?
    If at first you do succeed, try something harder.

    I agree withprtech
    user-offline.png there is definitely something going on with PPP authentication. check to make sure username and password is correct.
    Check Protocol Encapsulation..

    Like goldenlight said, check the username and password. Based on the config you posted, you do not have that configured.

    thank you guys, I configured the username and password in the router..

    when I check the interfac of s0/0/1, i get this

    Serial0/0/1 is up, line protocol is down (disabled)

    I wanna ask, what is the problem when LCP is closed

    hmm..... I think I found the problem.. interface Serial0/0/1
    bandwidth 64
    ip address 172.57.1.214 255.255.255.252
    encapsulation ppp
    ppp authentication chap
    ip nat inside
    clock rate 64000 <
    Could this be the problem

    I noticed you have the clock rate set to 2000000 on the other Serial ports

    looking over your config in more detail I see PPP Authentication is configured on only one router.

    Thanks for helping me prepare for my ICND2 Exam icon_smile.gif

    Post your current config and config of other router.

    Post your CHAP authentication configs from both routers.... remember you use the other side of the links' username with the same password.
