Separation of locator/ID is a fundamental architectural principle which tra=

Controlling routing-table excursion in the IPv4/IPv6 Internet was/is the ta=

In light of the above, I view LISP and RFC6296 as orthogonal to one another=
. =20
I also view RFC6296 as a perpetuation of the clear violation of the end-to-=
end principle (i.e., ' . . . functions placed at low levels of a system may=
be redundant or of little value when compared with the cost of providing t=
hem at that low level . . .') embodied in the abomination of NAT/PAT into I=
Pv6, and the consequent instantiation of yet more unnecessary and harmful s=
tate into networks which are already deep in the throes of autogenic thromb=
oembolism.
