This is a high-level task to track the work to bring our new Nokia switches into the traffic path. At the end of this process the Nokias should be acting as the L3 gateway for the existing Vlans in Eqiad rows C/D, and those vlans will exist across the existing Juniper virtual-chassis devices and their Nokia replacements. This will leave us in a position where a host can be connected either to the Juniper or the Nokia on the same Vlan, allowing us to begin the work of migrating server connections from the old to the new switches.
