Abstract:
Route Leaks are 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
according to some configuration options without any check of 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, internal) relationship of two BGP neighboring speakers to
enforce appropriate configuration on both sides. Propagated routes
are then marked with a flag according to agreed relationship allowing
detection and mitigation of route leaks.
