NxT1 Config (MLPPP help)

[quikcheck]

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:

Thanks everyone for your help and patience.

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.

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!

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.
