Title : Bounding Longer Routes to Remove TE
Author(s) : S. Hares
Filename : draft-white-bounded-longest-match-02.txt

Some ASes currently use length-based filters to manage the size of
the routing table they use and propagate. This draft explores an
alternative to length-based filters which allows for more automatic
configuration and which provides for better redundancy.
Rather than use a filter, this draft proposes a method of modifying
the BGP [RFC1771] longest match algorithm by setting a bound on the
prefix lengths eligible for preference. A bound would operate on
long prefixes when covering route announcements are available; in
certain circumstances it would cause a router to prefer an aggregate
over a more specific route announcement.
