Vlan Routing - Static Routes

Question

This is a newbie question...I'm sure....but here it goes.  Thanks in advance for advice! I have two Dell Powerconnect 6248 switches that I'm using as my 'core' switches. They are not stacked.  Instead, I have them trunked between the stack ports. At the moment - I am not using any layer 3 functionality on the boxes.  I have 5 separate vlans on them. All of which are private - 192.168.x.x networks. I'd like to be able to create a 6th vlan - for a public IP network....and connect a port on that VLAN6 to my Cisco 7204.  This Vlan would be 'on net'. I know that I have to configure the 'interface vlan x' and assign an IP address to that vlan.  However - what I'm not sure about is when I enable 'ip routing' for that Vlan only....how do I default traffic across that interface to the 7204? If I include a default route on the switch - out the public IP interface...how will that affect the private vlans? I just want to make sure that these networks are separate...and that anything I turn on 'routing' wise on the new public network - doesnt' affect the private network. Again - thanks for any assistance!

One of the first things to do to help ensure things are running as smooth as they can be, is to update the switch firmware. The current version 3.3.4.1 is available from this link.

Once you turn on routing on the 6248 then the all the VLANs on the 6248 will be able to communicate back and forth on layer 3.

You can set up ACLs to block traffic once routing is enabled. Here are some articles about setting up ACLs on the switch.

You would set up a static route with this command.

console(config)# ip route 192.168.6.0 255.255.255.0 10.0.0.2

This would direct the 192.168.6.0 class C traffic to 10.0.0.2

Hope this helps,

Keep us updated if you can.
