Abstract:
   Route leaks are the propagation of BGP prefixes which violate
   assumptions of BGP topology relationships; e.g. passing a route
   learned from one peer to another peer or to a transit provider,
   passing a route learned from one transit provider to another transit
   provider or to a peer.  Today, approaches to leak prevention rely on
   marking routes by operator configuration, with no check that the
   configuration corresponds to that of the BGP neighbor, or enforcement
   that the two BGP speakers agree on the relationship.  This document
   enhances BGP OPEN to establish agreement of the (peer, customer,
   provider, Route Server, Route Server client) relationship of two
   neighboring BGP speakers to enforce appropriate configuration on both
   sides.  Propagated routes are then marked with an OTC attribute
   according to the agreed relationship, allowing both prevention and
   detection of route leaks.
