This document clarifies the use case for that, defines a new Tunnel Label Stack sub-TLV for a label stack to be pushed AFTER other labels (e.g., the label embedded in the NLRI for a labeled address family, and/or the stack in an MPLS Label Stack sub-TLV), and defines two new Segment sub-TLVs to encode a segment list in a compact format.}, }
