I've done a lot of research on setting up additional VLANs on this hardware, and I've successfully implemented without any problems, once I wrapped my head around the process.
I'm going to change the default VLAN to some obscure number (4095, or something in that high range) and move all the ports OUT of the default and into all the other VLANs that I've created. This would include the uplink ports. To preemptively answer the obvious question: yes, these VLANs have been defined properly on my EdgeRouter.
I've tested this very successfully on lab hardware. Just wanted to ask if anyone knew of any issues with this before I pull the trigger on my production environment?
