I disagree. You are describing a generic technology with vendor specific terminology. How packets move (if they move at all) in a router is an implementation specific detail (that is to say it's up to the box designer and internal to the device itself) . > I personally view the sole distinction between the standard routers/bridges >and the multilayer switches as the use of ASICs. How a technology is implemented does not change the nature of the technology itself. By this definition, I would be curious at what forwarding rate does a router becomes a switch? In other words, just because some IP routers are faster than others does not mean they are not routers. Of note, most high end routers implement an all silicon based forwarding path and few of these folks have branded their routers as switches. >scott Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=65476&t=65215 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
