RE: PPP link negotiation problem [7:31132]
what about ppp chap sent-username ? -Original Message- From: bergenpeak [mailto:[EMAIL PROTECTED]] Sent: 07 January 2002 13:09 To: [EMAIL PROTECTED] Subject: PPP link negotiation problem [7:31132] I'm working through the different ways one can configure CHAP authentication between two routers over a PPP serial link. If I configure ppp encap and ppp chap authentication and both sides of the link and use the global: username password for identification, the link comes up and IPCP is established. The routers have hostnames defined to be "rtr-2505" and "rtr-2514". When I try to use the "simpler" CHAP config, where one can encode in the interface directly the same hostname and password, I see the error: PPP Serial0: Using alternative CHAP hostname something PPP Serial0: CHAP Challenge id=14 received from something PPP Serial0: ignoring challenge with local name On both rtrs I have the following defined on the serial interface: ppp encap ppp authentication chap ppp chap hostname something ppp chap password else there are no usernames defined globally. Ideas?

Re: PPP link negotiation problem [7:31132]
"sent-username" is not an option for me under ppp chap. My options at "ppp chap" are "hostname", "password", "wait", and "refuse".

Your only choice is to use global username other router and password the sama as your router they must be identical on both sides.

Re: PPP link negotiation problem [7:31132]
Thanks for the responses so far. I still don't understand the purpose of the "ppp chap hostname" command under the interface config. Using this command, I am now able to get a PPP link up. But I must do the following: rtr-a config: username rtr-b int serial 0 encap ppp ppp chap hostname rtr-a rtr-b config: username rtr-a int serial 0 encap ppp ppp chap hostname rtr-b That is, I must define the hostnames to be *different* on each side, and then define the corresponding global username to match the remote hostname on each side of the link. Thus, the interface "ppp chap hostname" command doesn't appaear to simplify the CHAP config. This seems to defeat the purpose of this command as suposedly it's used to simplify the CHAP config so that the same hostname can be used on multiple routers. Or so its stated in the ICRC book (page 373). So, I'm not really sure what benefit there is for this command, as it doesn't seem to simplify the config. But I'm sure I'm missing something... :-) Thanks for any more info/comments.

RE: PPP link negotiation problem [7:31132]
I agree! From what I've read, that's not how it's suppose to work! This link came through the list recently! http://www.cisco.com/warp/public/131/ppp_callin_hostname.html I'm not sure if you've seen it or not, if you have, I apologize for not reading the entire thread! If you haven'tcheck it out! If you can't get to work as advertised, post your results, and I'll try and see what happens! -Stefan -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of bergenpeak Sent: Wednesday, January 09, 2002 10:26 AM To: [EMAIL PROTECTED] Subject: Re: PPP link negotiation problem [7:31132] Thanks for the responses so far.

Re: PPP link negotiation problem [7:31132]
The benefit is that you can use names other than the hostname of your router that is the only purpose of the command.

Re: PPP link negotiation problem [7:31132]
Thanks for the URL, Stefan. That link explained why this command might be useful. In the context I was dinking in (p2p serial), this command has little value. Stefan Dozier wrote: > > I agree!
