Abstract Abstract
There are a variety of BGP-enabled services in which the originator 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. 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), 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 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 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 (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 route R if and only if B has announced interest in one of the RTs
