question to PAP

Hello,

when i use the PAP authentication i use the term:

username XXXXXX password XXXX

the username is the Router-name but where does the Password comes
from? When i implement this on the accessing router, where do i have
to specify the password in the accessed router?

when u implement the usernamexxxxxpasswordxxxxx
this is for the router you want to access not your own password so this other router will have a similar global statement but with your username and password. See the technotes for a more in depth explanation.

That is my question!

I guess i have to define an password for both routers.
In one Router(call it A) i have defined the username and the password of
the Router (call it

that want to access.
But where do i have to say that RouterB should use password XXXX to authenticate in Router A.

Should i define the same password on both Routers but with the Routername of the other router as username?

RouterA: username RouterB password cisco
RouterB: username RouterA password cisco

Is this correct??

Remember, that is for configuring PAP/CHAP for two way authentication, it's different when using authentication for just one way. Here is what Cisco has to say:

PPP pap sent-username <username> password <password>

Enables outbound PAP authentication. The local router uses the username and password specified by the ppp pap sent-username command to authenticate itself to a remote device.

The other router must have this same username/password configured using the username command described above.

Why bring this up? It was a question on the practice CCNA exam I took at the end of the networking academy. The more bizarre thing is that it was specified in the networking academy books....weird.
