RFC 4023: Encapsulating MPLS in IP or Generic Routing Encapsulation (GRE)

Still current, but amended. Parts of this document are changed or extended by RFC 5332. Read both.

In plain English — editorial summary, not part of the RFC

Various applications of MPLS make use of label stacks with multiple entries. In some cases, it is possible to replace the top label of the stack with an IP-based encapsulation, thereby enabling the application to run over networks that do not have MPLS enabled in their core routers. This document specifies two IP-based encapsulations: MPLS-in-IP and MPLS-in-GRE (Generic Routing Encapsulation). Each of these is applicable in some circumstances. [STANDARDS-TRACK]
