Unable to remove a vlan from the default route domain

Hi Sarah!

Sorry for the late reply. I live in Sweden so my time zone is CET.

Partitions is more of compartmentalization of parts of the configuration. Objects in Common is available to all partitions, while objects in the individual partitions is only available within that partition (there are exceptions, like referencing objects in iRules by absolute path. Ie "pool /Mypartition/mypool").

When having a large F5 configuration, or using route domains, partitions is really great as it allows you to only see the configuration you need at the time.

After looking at your drawing and thinking a bit I'd say route domains is better than the FastL4 VIP I mentioned. Since you need to separate traffic between DMZ and an internal VLAN there's a security factor as well and hence route domains would work better. Better prepare some aspirin though as they could indeed cause head aches. :)
