How is this an OSPF problem? Do you have the clock rate configured? Paste your configs here or upload your packet tracer file.

my friend told me that it's the protocol, i already configure a clock rate

thank you for your help

prtech

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?

pattyricia_08

uhm, when i type debug pp authentication s0/0/1 is closed

what is missing, another clue please

goldenlight

I agree withprtech

there is definitely something going on with PPP authentication. check to make sure username and password is correct.
Check Protocol Encapsulation..

prtech

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

pattyricia_08

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

goldenlight

hmm..... I think I found the problem.. interface Serial0/0/1

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

FloOz

config for other router?

prtech

Post your current config and config of other router.

xXErebuS

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