I'm loath to continue this discussion, but I do have a
question for Kelly.
Why do you have a VLAN at all in your example?? Isn't a
single VLAN sort of
like one hand clapping? Seriously, what role is it playing
in your network

Does that make a 7500 with VIPs a L3 switch? A 12000 with
distributed forwarding processors?
Substituting router for L3 switch is a good idea, but go farther than

you are doing a bit of confusion:
so does layer 3 switching require the use of VLANs to actually do
the switching?
It's true the contrary case: the Vlans requires L3 to be routed, or, in

good for you, Cil. This discussion was ( and still is, to judge from my
in-box ) filled with misdirection and poor information. Cisco and all the
other vendors are absolutely to blame for this.
a router is a function, not a device
so is a switch.
what does it matter where the function resides,

one may also configure the physical interfaces as L3 interfaces - just as

Stephen,
You're getting there. Let me give an example of how VLANs are used
(I'd draw a picture, but it probably wouldn't look good).
For this example, let's use two of the colleges on my university
I am studying for the CCNP Switching exam and it covers VLANs and layer 3
switching moderately. It states that Cisco recommends a 1 to 1 mapping of
VLANs to subnets. It also states that VLANs can be used to break up
broadcast domains.
When you create different subnets, you are already breaking up
36 matches
