Re: [RRG] Evolutionary Possibilities



Thanks for the response Ran. Just one brief comment below.

CAVEAT:
  As I have said here before, it isn't obvious to me how one
could implement a true I/L split scheme in IPv4.  The challenge
is where to put the Identifier values if one can't use IPv4
options.  (Using IPv4 options is a non-starter because it forces
the packet to be slow-path forwarded in nearly all current
implementations.) [2] [3]

This is why LISP for IPv4 chose encapsulation. There really was no other choice.
