I am looking at having multiple networks created at the same premise. Each one will run a zone with work stations and servers. I am a bit confused between multiple routers and a layer 3 switch ? What do you guys suggest ?

Software/Hardware used:
switches, workstations running linux, three wan links

Thanks. We'll let you know when a new response is added.

The primary difference (there are several) between a router and a layer-3 switch is that the layer-3 switch does much of its work in specialized hardware for greater speed.

Layer 3 switches are generally best in an environment such as you describe – where everyone is local and all the traffic is high speed.

Routers are best for WAN applications where there is a significant change in the media being used (T-1, Frame Relay, other wide-area schemes).

That’s the simplest answer.

    Sorry - Hit the "Continue" button too quickly. You can also use the L-3 swtich to direct in/outbound traffic to your WAN routers. Bob
