Since you are from Cisco...so it is your opinion that a Catalyst 6509 (i.e. Layer 3 switch) is equivalent to a 7206 or GSR? Of course, this is in regard to 'core' routing device in the middle of a national IP network. This network in question just happens to utilize a lot of GE LH interconnections. --- "Stephen Sprunk" <ssprunk@cisco.com> wrote:
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
Thus spake "ip dude" <ipdude@cattle-today.com> 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.
