Extensions to BGP-Signaled Pseudowires to Support Flow-Aware Transport Labels

This draft defines protocol extensions required to synchronize flow label states among Provider Edges PE(s) when using the BGP-based signaling procedures. These protocol extensions are equally applicable to point-to-point Layer2 Virtual Private Networks (L2VPNs). This draft updates RFC 4761 by defining new flags in the Control Flags field of the Layer2 Info Extended Community.
