This document discusses a Generalized Multi-Protocol Label Switching
(GMPLS) Resource reSerVation Protocol with Traffic Engineering
(RSVP-TE) mechanism that enables the network to assign an upstream label
for a bidirectional Label Switched Path (LSP).  This is useful in
scenarios where a given node does not have sufficient information to
assign the correct upstream label on its own and needs to rely on the
downstream node to pick an appropriate label.  This document updates
RFCs 3471, 3473, and 6205 as it defines processing for a special
label value in the UPSTREAM_LABEL object.

This document is a product of the Traffic Engineering Architecture and 
Signaling Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this
