Indeed, current PPP doesn't not allow for ip-less interfaces. But as you
said, the important part is not having routes through the physical
interfaces. I know pppd (or the kernel) will create those routes
automatically, you need to delete them manually or in the ip-up script.
When I did the same thing with two async PPP interfaces (2 modems), I
initially gave them the same IP address and also gave the same IP to the
teql interface. That worked fine, except gated wasn't very happy about it
so I ended up changing the IP addresses on the interfaces to things like
10.0.0.x. It didn't matter anyway since no routing was involved, the only
peculiar aspect of all this was that 10.0.0.x was appearing in the
traceroute output.

And you should definitely be able to do that. But first you need the teql0
up and configured with an IP address.

Right.

Yes. Absolutely.

Which makes sense, an interface without an IP address is essentially an
interface incapable of handling IP traffic.

You need an IP for teql0.

You're welcome. :-)
