I am planning the configuration of a new network using 4 new switches and using a layer 3 Dell powerconnect 6224 to route between the different VLANs and the external network but I am not entirely sure about how to set up the intra vlan routing etc and was hoping that someone could give me a few pointers.?
Basically I am ok at to create the VLANs etc on the switches and from what I have read that I need to enable IP routing on the layer 3 switch using the "enable ip routing" command but I am unsure about setting the default gateways etc.
I am planning on using a gateway appliance and want all outbound traffic to go through this device. Do I set the IP address of the gateway appliance as the default gateway for all of the VLANs etc or do I create a default route on the layer 3 switch?
I was under the impression that I cannot configure a default gateway that is on another subnet so I am wondering what the best approach is in this situation.
Any assistance in helping me clarify this process would be most appreciated.
