NxT1 Config (MLPPP help)

Hello everyone,

I need some help configuring MLPPP for an NxT1 (3MB) for internet access. My ISP will not support me with the config unless they supply the router and I don't know anything about MLPPP configs except for what I can find on the cisco support site, etc. They haven't installed the circuit yet, so this is obviously just a pre-configuration, but does it look like this should work? Obviously, I am making a couple of assumptions (no CHAP, etc).

This is what I have come up with so far:

Since we do not know what router platform or what card is being used, it is difficult to comment on specifics of what is required. If you found a reference on the Cisco site that indicates that you need it, then perhaps you should leave it in - at least until you have a chance to bring up the circuit. If there appears to be anything strange about the operation of the circuit removing that statement would be one of the first things that I would do.

I can also say that I have configured a number of routers with service-module commands under the serial interface and I do not believe that I have needed to code pulse time on any of them.

Just to clarify a bit, the provider is willing to supply a router to do multilink and would do configs for it, but they are not willing to help with configs if it is not their router. Is this a correct understanding? If it is your router and you have done the configs, will they do multilink (they just take no responsibility for your side)?

I have looked through the config - looking harder at the serial and multilink parts. I think that mostly it looks reasonable. I do not usually use the command pulse-time 6. I am not sure why you need it. Otherwise it looks ok to me. And I certainly agree with your assumption about not doing CHAP. I see little point in authenticating a point to point private circuit.

Re: NxT1 Config (MLPPP help)

Rick,

You are correct about the ISP. I am sure they will give me the specifics regarding ISP-specific settings once the circuit is installed, but they just won't help me do the initial config of the router. They will do multilink (I bought a 3MB circuit, and they said it uses MLPPP).

As far as pulse-time 6, the cisco site I saw indicated that i needed to put that. If you don't think it's necessary, I am going to remove it.

Thank you VERY much for your help!
