advertised/routed over v6.


Don't advertise v4 prefixes in v6 sessions, keep them separate.

If you do, you have to do set next-hops with route maps and things, it's
kind of nasty.

Better to just run a v4 BGP mesh and a v6 BGP mesh.

Ok. I've been having problems with this.

What I was hoping for (even though I'm testing something that I know
won't work) is that I can break something so I could push v4 traffic
over a v6-only core.

Is there _any_ way to do this (other than NAT/tunnel etc)?
