This specification combines prior work on encapsulating MPLS in IP,
by Tom Worster, Paul Doolan, Yasuhiro Katsube, Tom K. Johnson, Andrew
G. Malis, and Rick Wilder, with prior work on encapsulating MPLS in
GRE, by Yakov Rekhter, Daniel Tappan, and Eric Rosen. The current
authors wish to thank all these authors for their contribution.
Many people have made valuable comments and corrections, including
