SGE 2000 Inter VLAN Routing

Hi,

I had to propose SGE2000 as a layer3 switch to one of my customer due to budget constraint now customer has asked clarification on following points:

a) Does SGE 2000 supports Inter VLAN routing feature, if yes (see point b)
b) Inter VLAN routing is a feature of only L3 or it is available in L2, i am asking because customer is asking as a L3 feature and i do not about this.
c) Does it support static routing (This i have checked in data sheet, it is available)
Regards

Re: SGE 2000 Inter VLAN Routing

Hi,

a) Does SGE 2000 supports Inter VLAN routing feature, if yes (see point b)
Yes, the purpose of an L3 switch is be capable of routing, once you have 2 VLAN, they must be in different networks, the only thing that you have to do in the SGE is a static route between these VLANs(networks).
b) Inter VLAN routing is a feature of only L3 or it is available in L2, i am asking because customer is asking as a L3 feature and i do not about this.
VLAN routing, when we say routing we mean Layer 3.
c) Does it support static routing (This i have checked in data sheet, it is available)
As you said, yes, it supports static routing.
I hope it was helpful.
Please let me know if you need something else or if I didn't asnwerd as expected.
Regards.

Re: SGE 2000 Inter VLAN Routing

Hey csco, one thing about these switches with the layer 3.  When in layer 3 mode, don't think of it as vlans but networks.  It is possible to have multiple networks connected to the switch and create static routes to route the traffic for the networks.  In layer 2 mode, you can incorporate multiple vlans and in order to get the vlans to communicate between each other, you need a router that understands the vlans and connect it to the switch via trunk port.  So with layer 2, you need a vlan capable router with a trunk port to the switch.  With layer 3 supposing you don't have a vlan capable router, you can do multiple networks and do static routes to the router and routes back from the router to the switch for the multiple networks.  The main thing between the two is in layer 2 the router handles the switching for the vlans and in layer 3 the switch does the routing.
