First, this is in no way a troll; nor is it a criticism. I'm not
qualified to criticise.
I'm curious: what is it about the cisco router that makes it
preferable to a ``normal'' computer (i386, Sun, whatever) running
OpenBSD for this application? I can make guesses--hardware being
at the top of the list--but I've never had to deal with networking
at this level so all my guesses would be completely uninformed.
Would it be possible to use OpenBSD in this situation at all? If
so, what would it look like? I have in mind a computer with one or
more fast PCI busses and as many quad ethernet cards as will
physically fit...but, again, this is out of my league (which is
why I'm asking).
Might OpenBSD be a reasonable fit in some similar situations to
You could. But routers don't have disks, so no storage to fail. Routers
have custom OS which is specifically designed for routing. Routers have
tcp/ip stack specifically tuned for routing. Routers have redundant
parts and special risc cpu's. Sure, you could use a unix box, but
routers are just better and faster.
Also, you don't just need eithernet cards. You need DSU/CSU modules.
You can get 2 or 3 intel gigabit eithernet cards, put them in a box,
attach a 512mb flash chip as a drive and install a really lean linux or
openbsd install. Then run gated or zebra and pf/netfilter and have a
pretty decent router. I think OpenBSD supports some PCI DSU/CSU modules,
but they're somewhat expensive, $1000 or so...
Something like this maybe:
