Sprint never used cisco 4000s in the backbone. Just FYI.
Historically, memory limitation was because CSC/4 board in AGS/+
routers had memory soldered in. The box was absolute top of the line
when it started to fall over.
Not to mention the obvious problem, the routing table was growing
exponentially. I don't care how much memory you put in a box, if
we hadn't solved that problem, the game would have been over.

This statement shows that the level of comprehension of the issues
remains absymally low.
It is NOT memory; it is CPU which is a limiting factor. Even the
mainframes would keel over on routing computations if the drastic
measures weren't taken to aggregate and dampen.
