Hi Khalil,
Thank you and all the others for providing help on this. The command ppp pap
sent-username is the one that worked. Thanks a million to you. I am
puzzled-I was following instructions from books(won't mention which) and
none of them had this command!! Here is what I found out...very interesting.
2 routers, RouterA and RouterB connected back to back.
RouterA 1.1.1.1 DCE
username RouterB password cisco
encap ppp
ppp auth pap
ppp pap sent-username RouterA password cisco
RouterB 1.1.1.2 DTE
username RouterA password cisco
encap ppp
ppp auth pap
ppp pap sent-username RouterB password cisco
This command is reqd. on BOTH routers. If this command if entered on only 1
router, the serial on the other starts flapping!!! strange!!
If NOT entered, the BOTH serial report line prot. down!! strange!!
But if configured with chap, ppp chap sent-username.....is NOT reqd. It
works fine!! strange!!
My only explanation could possibly be is that since pap sends the password
to the other side, the other side needs to know who is coming in with what
password and compares this to the local username and password. I wonder what
would happen if I did not have the local username and password set??
Would anyone be kind enough to explain why this configuration is such??
Thank you.
Kind regards,
