I'm familiar with the multiple tables options.

I will write (rant) more on this elsewhere as I approach solutions....

A complete solution would require changes to the protocol.


 yep. I was trying to come up with a sane set of filters using
the filter rules, and failed.

I'm not sure what, if any, routing protocol, can handle the source routing
complexity inherent in ipv6, at present. 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...
