Well, if you want auto-mode, the PPP process needs an IP address of
the remote side in advance, so it knows which packets are about to be
routed through itself, so it in turn can dial if required.

That's usually done with a

 set ifaddr 0.0.0.0 <hisaddr>
 add 0 0 <hisaddr>

I think you can specify a number of significant bits for <hisaddr> in
the `set ifaddr' clause, too, so the actual remote address will be
negotiated once it has been dialling out.

The `add' command adds a default route so all packets destined for the
outside will be passed to the PPP process.
