RFC 3476    LDP & RSVP Extensions for Optical UNI Signaling   March 2003


2. LDP Extensions for UNI Signaling

   The LDP extensions for UNI signaling consist of new TLVs that capture
   UNI-specific parameters and new UNI-specific status codes.  The new
   TLVs are Source ID (3 TLVs), Destination ID (3 TLVs), Egress Label,
   Local Connection ID, Diversity, Contract ID, and UNI Service Level
   [8].  These are described below.  The new status codes are assigned
   from the private use space of LDP codes, as described in [8].  The
   UNI specification [8] also defines two new LDP messages, Status
   Enquiry and Status Response.  These messages have been obsoleted and
   hence no code points are requested in this document for them.

2.1  Source ID TLVs

   Three TLVs have been defined to encode the Source ID. The content and
   usage of these TLVs are described in [8].
