</div>The setup you describe is easy to get to work using just a little bit of<br>

A complete solution would require changes to the protocol. </blockquote><div><br> yep.

I've<br>
considered them in an earlier version (protocol version 1), and finally<br>
decided they're not worth the extra complexity.<br>

And it would be nice to have multiple potential ipv6 gateways to the internet, but reject routes to invalid destinations long before they get there, while still be able to distribute default routes, and still be able to route 'behind' the main gateways in a mesh...<br>
