Layer 3 Switching vs Routing
LockedHello All, I’ve been a lurker for years, but finally registered specifically for this question. I have been assigned the task of aiding in the design for a new WAN to connect 25 schools together via new fiber that’s about to be installed at each location. We’re currently using T1’s to connect all locations to a central location that houses a DS3. Those T’s simply cannot handle the bandwidth requirements anymore. So, we’re in the process of having fiber pulled between all locations. We will continue to use the existing routers (Cisco 1721’s) and the T1’s for redundancy to our fiber, once completed.
The big question that I need answered is this: Should I use layer 3 switches, or routers, to connect all of these locations together, but keep them segmented from each other? I’ve read the pros and cons of both devices and still cannot decide which would be best for this project. From what I’ve read, layer 3 switches are less expensive and generally have quicker throughput in comparison to routers. Based on your real-world experience, which would you recommend and why? I’m not biased to any manufacturer, but cost is an important factor for this school district. Your replies are truly appreciated!
