Abstract

   This document specifies mechanisms and TLVs (Type/Length/Value) for
   support of CR-LSPs (constraint-based routed Label Switched Path)
   using LDP (Label Distribution Protocol).

   This specification proposes an end-to-end setup mechanism of a CR-LSP
   initiated by the ingress LSR (Label Switching Router).  We also
   specify mechanisms to provide means for reservation of resources
   using LDP.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [6].
