add text to make clear this topology may change and that sites can connect to both VLANs

The initial Spiral 3 GENI network core is a set of OpenFlow-capable switches in NLR and Internet2.

There are currently two standing VLANs (3715 and 3716) carried on the ten switches in the core, which are located in the nine cities shown on the maps below. Each VLAN in each provider is topologically a broken ring (to help prevent accidental loops), with the two rings in each VLAN linked in Atlanta. The gap in each VLAN is between two different links, to provide either a longer or shorter path through the core between two switches. The two VLANs are not interconnected in the core, and should not be interconnected in regionals or at GENI sites either. Sites may connect to both VLANs as long as the site keeps them separated at layer 2.
