"routing table slots" and the real problem

Yet again people keep talking about "the size of the routing tables"
as being the deep problem, and this makes people say silly things
like "FOO is protecting router memory".

Thinking about it this way is funamentally and fatally incorrect.

The REAL problem is the growing complexity of the ROUTING COMPUTATION,
not the size of the resulting forwarding table. even if routers
had infinite memory, we would still be crushed by the routing
computation if allowed to grow unchecked.
