Why would you not trust a Linux box to route? What experience or
documentation do you have that would lead you to believe that a properly
configured Linux box could not or would not do the job. There are a lot of
companies using Linux these days. One of largest distributed processing
systems is based on large linux clusters, most of Mariott's reservation
system is based on it. Lot's of ISP's use it as their core e-mail, and web
systems, and I have seen some departmental use of Linux or Windows NT
machines being used as routers.
A cisco router is not that much different in architecture. At the highest
level, It is a processor that runs a unix kernel based OS with some NIC or
serial interfaces and an application designed specifically for routing. The
real difference is in the software that runs on the router. There is no
special ASIC's or processors on the router. IT is a computer (less intel
pentium processor except in the PIX) w/o the added multimedia and I/O
hardware, driven by a unix kernel running software , very similiar to any
other computer. The real difference is in the application, or software it
runs, not it's hardware architecure.
My understanding is that some of the processors found in the router are the
same that can be found in certain Apple or Macintosh PC's and other
non-windows based cpu's.
This is my humble opinion based on my limited knowledge of the router
architecture. However I agree that it would not be appropriate to place a
linux box at the core of your network there are certainly times or
applications and solutions where it would be fine. It is not designed
specifically for routing, but it will certainly do the job if simple routing
is all that is needed.
