It's all about the DCI. Do-do-doo.

After listening to this brilliant podcast about Alex's thrilling adventures around connecting three DC together I've unexpectedly found that I have a serious gap in data center interconnect technologies. What's more, all involved protocols such as VXLAN, MPLS, GRE, VPLS are pretty clear for me. Well, there always is a room for improvement. See the table below putting all of them under the same roof (actually it's a note for myself rather than article). The main question is a control protocol for MAC addresses exchange. I don't mean one for underlay network. Without any we should flood our packets and lose an isolation.  Having one we can switch off BUM packets and use only ARP with cashing. The exception is TRILL-like Fabric Path which doesn't inhibit flood.
