Rather than offer a counter argument I would like to point out that
the same argument had been made as far back as the introdcution of
NHRP to the ROLC WG wrt signalling implosion at a router serving a
major portion of the non-ATM or non-"the-same-NBMA" portion of the
Internet.  The problem was never resolved and I do not even remember
hearing a credible counter argument at all.  This problem was simply
ignored by the WG just as some tried to ignore route loop
possibilities.

Perhaps now that "large cloud" is no longer part of the WG name, the
WG chair will see fit to officially sweep the problem under the rug.  :-(
(English coloquialism for ignore rather than address a problem).

NHRP does offer a solution to the problem of "cut-through" with
limited ability to scale, much like RIP offers a solution to the
problem of routing with limited ability to scale.  Both are poor
general solutions but have applicability.  It is unfortunate that this
WG has been short sighted and unwilling to consider technical
arguments that do not favor a predetermined direction.
