With companies one of the first questions that I think some people forget to
ask is if a routing protocol is really necessary for the network topology that
they have. Routing protocols are only really useful for when you have multiple
paths out of your particular subnet. If you only have one path out then using
any routing protocol is needless.
That may seem like common sense, but I used to work for one large employer who,
because the network admins weren't too bright about routing, used ospf on every
router they had to link all their buildings. Even though each router only had
a single T1 connecting it directly to the core router at the noc and that
router had a direct 10/100 link to the upstream providers router. I'd tell
more, but I think some people here would think I was bullshitting.

I guess this is a start:
http://en.wikipedia.org/wiki/List_of_network_protocols
In the list of protocols, some are better suited for smaller Enterprises
and others are better for bigger Enterprises.
That's my 2 cents. I'm sure we'll get some better pointers from some of
the more 1337 SecurityFocus members :-)

Hi
Does anybody have an overview which shows which routing protocols are
used in the Internet and which one within Enterprises only?
