Abstract:
   There are a variety of BGP-enabled services in which the originator
   of a BGP route may attach one or more "Route Targets" to the route.
   By means of a procedure known as "RT Constrained Distribution" (RTC),
   a given BGP speaker (call it "B") can announce the set of RTs in
   which it has interest.  The implication is that if a particular route
   (call it "R") carries any RTs at all, BGP speaker B wants to receive
   route R if and only if B has announced interest in one of the RTs
   carried by R.  However, if route R does not carry any RTs at all,
   prior specifications do not make it clear whether B's use of RTC
   implies that it does not want to receive route R.  This has caused
   interoperability problems in the field, as some implementations of
   RTC do not allow B to receive R, but some services presuppose that B
   will receive R.  This document updates RFC 4684 by clarifying the
   effect of the RTC mechanism on routes that do not have any RTs.
