Thus spake "ip dude" <[email protected]> > IP Community: > > When designing an all IP network requiring mostly Ethernet interfaces, the logical conclusion is to specify layer 3 switches (instead of routers). The cost per port and functionality requirements make a layer 3 switch the perfect choice. However, the rule of thumb in the IP community is that routers are superior to layer 3 switches and should be utilized instead, especially when considering core type functionality. > > Does this rule of thumb still apply considering the modern layer 3 switches available? If not, why? What makes a layer 3 switch sub-standard to a pure router? Any quantitative analysis you could provide would be greatly appreciated. "switch" is a marketing term meaning fast, nothing more. Any device that operates at Layer 3 is a router by definition. Therefore, "Layer 3 switch" means "fast router". Now think about your question again. S
