ETR Address Forwarding (EAF) is a novel method by which an IPv4 Core-
Edge Separation solution to the Internet's routing scaling problem
can tunnel packets from an ITR to an ETR. EAF involves using 31 bits
of the IPv4 header for new purposes: bit 48, the More Fragments flag,
the Fragment Offset field and the Header Checksum field - to carry a
30 bit ETR address. Consequently, packets in this format need to be
handled by routers with upgraded functionality. EAF is an
alternative to encapsulation and has advantages including: simpler
ITRs and ETRs, direct support for conventional RFC 1191 PMTUD, no
encapsulation overhead and full compatibility with IPsec AH and
Traceroute. This I-D also briefly explores an alternative to this
approach: a new header, of the same length and different, with a
different 4 bit Version, to carry 31 bits of ETR address.
