Once upon a time Darrin R. Woods shaped the electrons to say...
>(208.10.136.0). Their router/nt1 (Ascend PL50) will be at .1. Our pm2i is
>at 208.12.177.28. We are putting all of our ISDN lines on a roll-over so

>/etc/raddb/users files for ISDN. Also, is there a way to restrict a dialin
>ISDN customer to just 1B?

username Auth-Type = "whatever"
Service-Type = Framed-User,
Framed-Protocol = PPP,
Framed-IP-Address = 208.10.136.1,
Framed-IP-Netmask = 255.255.255.0,
Framed-Route = "208.10.136.0/24 108.10.136.1 1",
Framed-Routing = None,
Framed-MTU = 1500,
Framed-Compresion = Van-Jacobson-TCP-IP,
Port-Limit = 1

The last line means 1 B channel only.

>least a subnet of it. I should also, I think, be able to set it up
>generically so that as we add 2i's or even pm3's that no matter where which

This entry will work. Note, however, that this can mess with you routing
something fierce. If all of the PMs are on the same logical net, no problem.

But if they sometimes call POP 1, sometimes POP 2, sometimes the home office,
how are your routers going to handle sending this C net in different
directions? OSPF helps a lot with this, but you'll still need to plan this
carefully.
