Re: Routing protocols, Internet vs Enterprises

[gjgowey () tmo blackberry net]

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?
