Abstract:
   Route leaks are the propagation of BGP prefixes that violate
   assumptions of BGP topology relationships, e.g., passing a route
   learned from one lateral peer to another lateral peer or a transit
   provider and passing a route learned from one transit provider to
   another transit provider or a lateral peer.  Existing approaches to
   leak prevention rely on marking routes by operator configuration,
   with no check that the configuration corresponds to that of the eBGP
   neighbor, or enforcement that the two eBGP speakers agree on the
   relationship.  This document enhances the BGP OPEN message to
   establish an agreement of the relationship on each eBGP session
   between autonomous systems in order to enforce appropriate
   configuration on both sides.  Propagated routes are then marked
   according to the agreed relationship, allowing both prevention and
   detection of route leaks.
