I have a wee puzzle on my blade enclosure (M1000) and switches (Dell 6220 x 4 ) with ex virternal Dell switches (6224 x 2). The Blades host VMware virtual machines. The current set up is: The 6220 switches have a number of VLANs which are combined in a single Trunk to the external 6224 switches which then go to their relative physical devices. The question now is: I need to add a DMZ to service my virtual servers, what are my options?
1. Create another VLAN on the 6220 switches and use the trunk to the 6224 switches and create a VLAN with no route to connect to the Firewall?
2. Create a VLAN on the 6220 switches and connect it directly to an aggregation switch then connect it to the Firewall?
3. Something Else?
Any help would be appreciated.
