We purposefully did not specify what the contents of a policy
constitute, or whether policies should have an implicit 'accept'
terminal clause or an implicit 'deny' terminal clause.

All we try to accomplish, is that if you configure _nothing_ for an EBGP
peer, the software will not advertise any routes or use any routes which
it receives. 

Kind regards,
