Abstract 

   This document specifies an additional IP-based encapsulation for 
   MPLS, referred to as MPLS-in-UDP (User Datagram Protocol), which is 
   applicable in some circumstances. This document only describes the 
   MPLS-in-UDP encapsulation.

Internet-Draft          Encapsulating MPLS in UDP        September 2013 
 
    
1. Introduction 

   This document specifies an additional IP-based encapsulation for 
   MPLS, referred to as MPLS-in-UDP (User Datagram Protocol). It also 
   describes the applicability of this encapsulation in presence of 
   other IP-based encapsulations for MPLS. 

   This encapsulation allows for two Label Switching Routers (LSR) to 
   be adjacent on a Label Switched Path (LSP), while separated by an 
   IP network. In order to support this encapsulation, each LSR needs 
   to know the capability to decapsulate MPLS-in-UDP by the remote 
   LSRs. This specification defines only the data plane encapsulation
