    abstract =  {{[}RFC9012{]} defines an MPLS Label Stack sub-TLV for Tunnel Encapsulation Attribute, and specifies that it is to be pushed BEFORE other labels. This document clarifies the use case for that, and 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).},
