As you may know, I've been working (along with Alvaro Retana of Cisco and others) on BGP benchmarking. Our specific goal is dealing with single devices, but those are the devices being measured -- we need multiple routers or router simulators to generate and receive forwarded updates.

I know several commercial scenario writers who believe in even more routers to add complexity. But there may be good reason for people to create 4 router labs for technology learning, unless you are dealing with something like hierarchical routing. Well-developed 4 router labs, whether personal or virtual, certainly would be cheaper. >I've found the >labs at www.fatkid.com to be an good resource >for this, along with the examples at >www.cisco.com on the TAC pages. > >Then to complete the circle, I'd love to >see a set of large scale labs that build >everything together.

Thanks much. Howard (I think my opinions are the opinions of Gettlabs, most of the time, except when they cost too much money.)
