The cisco comes with 1Mb of memory.  When I do a show mem, I find
about 450K total bytes and of that about 100K-200K in use, leaving
between 200-300K available.  What has happened to the other 500K?
Is that for the software?  How much room will be taken by a full
1023 node Decnet area routing table?  How much room does each access
list take up?  How much room do IP routing tables take up (RIP,
IGRP)?  Have people hit the wall yet of no more memory?  What type
of error messages does the cisco produce when one runs of memory?
 
Thanks,
Hank Nussbacher

I have run out of memory when having many interfaces (about 10) and
several routing protocols active on one router.  It printed something
to the console to note the fact.  In 8.2 you should be able to execute
the code directly from the PROM which frees alot of memory at the
expense of some loss in performance.  I would, however, recommend that
you buy csc-3 processor (which has 4MB of memory) for all new routers.
