PPP T1 Leased Line Serial Problems

[Dyehouse1]

We are running a current 1601 on a T1 over a serial connection. We are having problems setting up the serial connection side of the config. Can someone help out with a basic settings of a serial line for a PPP connection. We have been told to use 'ip unnumbered ethernet0' setting and PPP encapsulation - our ISP said we don't need PAP or CHAP or ANY! authentication - is this correct?

Many thanks

Sounds about right to me. Stick the IP on the E0 interface, do IP unnumbered e0 on the serial interface, encap ppp on the s0, and a default gateway pointing to the serial interface. That should do the trick for you.

The question is how can I set the gateway on the ethernet address?

Secondly can this be done with them both effectively having the same IP?

Do I need to log on with PPP ISP says I don't but seems a bit weird to me is this cuz we are equivalent of direct wired?

No you don't need to login, PPP is just a transport protocol, it can be configured not to use authentication. What do you mean about the gateway ethernet address for the ethernet side? Do you mean the gateway for the clients?

If its the route you're talking about do this "ip route 0.0.0.0 0.0.0.0 serial 0"

There are some limits with ip unnumbered, but if the ISP says to use it, then its okay.. I can't remember the exact limititations.


Hope this helps.

Well I have done everything you lot have said in my 1st attempt and so I guess its back to whine at the ISP.....this could get expensive if they want to send out a router guru! still I am sure they can furnish me with some more details. Thanks for the help guys.

According to our ISP this is a PPP authentication issue and he advises turning on the debug listing for the PPP and dialer. How do I do this and how do I look at the results?

thanks

If you are on the console, simply issue the command 'debug ppp authentication' from the enable prompt. If you are telnetting into the router, issue the command 'term mon' first. Todd Hethmon
