This discussion doesn't really belong on this list, but since Vadim
has told some untruths about gated needing more than 64MB of memory...

Most of the ANS routers run 32 MB and run gated. A few have 64 MB.
If we didn't have the scram utility holding it's own routing table
(used to load routes into smart cards), we could probably get away
with 32 MB almost everywhere. Yes - we do take full routing. The SGI
I am typing on has 32 MB and runs gated and takes full routing and
does full logging and I do compiles and other stuff with no problem.

The reliability of a Cisco is better, but PCs are not as bad as you
say. The manageability issue, I disagree with. I'd take the BSDI box
any day on that count. Just try expressing the policy on one of our
major ENSS routers on a Cisco. A BSDI box doesn't need a host to tftp
boot images and configs from (on the odd chance that you ever update
your Cisco software or have a config that doesn't fit into NVRAM) and
doesn't need a host to tftp logs to (on the odd chance that anything
ever goes wrong in a network and you need logging or tracing).

I don't think a PC today can realistically handle even one T1 at full
capacity. Also PC ethernet cards are sufficiently miserable that you
can only put one in a PC and get it to use the full ethernet
Makes a fine 56k router or a low end dial in PPP or SLIP server if you
can live with one ethernet. Beyond that, the PC hardware just isn't
Cisco doesn't make a laptop. :-)
