Agreed.  Keeping it separate works very well.  Can be the same interface
sure... but do it as a separate session.

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.
