  Yes, but FreeBSD can't have more than one gateway per destination.
There has been a patch for that, but it has been lost.  The routing table
simply lacks the ability to store more than one gateway.

  I really don't understand why you want to use Zebra and BGP to manage
the default route?  If you are using default routing, you really don't
need a routing protocol at all.  Typically if you are using BGP, you won't
even have a default route, because you'll have a specific route to every
destination.
