[nsp] AW: [nsp] Help with VLAN

Hi James

a) You could trunk one port of the switch to your router and handle on your
router
        all necessary inter-vlan traffic (often done)

        search on CCO for inter-vlan to find some sample configs for your job. You
might
        only face a problem with this approach due to the limited bandwith on the
trunked
        port, if you have mainly inter-vlan traffic. maybe monitoring bandwith with
mrtg
        (via snmp) on that port would be a good idea.

b) you can buy a l3 switch with is able to route inter-vlan traffic
internally

regards
arie

Betreff: [nsp] Help with VLAN

Hello,

      We are going to implement VLAN mainly to separate the broadcast
traffic from one segment to another.

      We have existing Cisco 2620 (one FastE port) and Cisco layer 2
switches. We have office users on one segment and some production machines
on another.

      Should I need a layer 3 switch for this connected after the router? Or
I only need the router to separate the two segments (using VLAN
configuration) on the layer 2 Cisco switches?

TIA,
James
