With BGP/MPLS VPNs any-to-any connectivity among sites of a given Virtual Private Network would require each Provider Edge router that has one or more of these sites connected to it to hold all the routes of that Virtual Private Network. The approach described in this document allows to reduce the number of Provider Edge routers that have to maintain all these routes by requiring only a subset of these routers to maintain all these routes. Specification of Requirements
