    abstract =  {This draft defines a new Outbound Route Filter (ORF) type, called the Route Distinguisher ORF (RD-ORF). The described RD-ORF mechanism is applicable when the VPN routes from different VRFs are exchanged via one shared BGP session(e.g. routers in a single-domain connect via Route Reflector).},
