<< Craig, I thought you should know better. >> What makes you say that? I have always claimed ignorance of networking technology, I was just asking a question. << Layer 3 is where routing is done. >> If you say so. << A switch is a Layer 2 device... a bridge >> Could be for all I know. My only comment was that I thought that Layer 3 switches were several times faster and at the same time cheaper than routers. It was my understanding that these switches were replacing routers. This story seems to back up what I was saying. "That threatens Cisco, because routing-switches are faster and cheaper than routers. " "Layer 3 combines the power of routers with the speed of switches." " Layer 3 products transmit data through the more sophisticated third ''layer'' of networking, rather than the standard second layer." (I'm just a techno-idiot but it seems like these switches are operating in the 3rd layer, not the 2nd). "Layer 3 switches are about five times faster than routers, but cost one-third the price, says Dataquest's Armstrong." "She says Cisco's new Gigabit Switch Router includes Layer 3 technology. It's a different way of filling the same needs that rivals are targeting with Layer 3 products, she says. " "Layer 3 routing-switches let customers move data faster and more efficiently." Sounds to me like Layer 3 switches are not exactly the same as a router but can replace or do some of the functions of a router better. Read it for yourself Message 3125256
