Really?  We have 44,934 network entries in our core right now from external
sources.  We also have used only about half of our 64M of RAM in our core
CISCO hardware.  The majority of that hardware can double that if necessary,
to 128M.

The ASCEND GRF400 can handle 150,000 routes with zero flap considerations.

See above, then please come back and explain the discrepancy.

Yep.  And by June there will be at least one other major hardware player
which we all know and love with an ASCEND GRF400-style device that also can
handle much larger tables and flap rates.
