Abstract
The present disclosure involves systems and methods for automating interconnecting or stitching disparate Layer 2 domains across data center interconnects without the need to renumber virtual local area networks (VLANs) within an existing network. The interconnected networks may allow components or virtual machines, such as containers, within the connected networks or data centers to exchange Layer 2 communications while the connected VLANs or fabrics retain existing VLAN identification numbers to minimize alterations made to the data center networks. Further, the process of interconnecting the data centers may be automated such that administrators of the networks may provide an indication of interconnecting the data center networks without the need to manually access and configure edge devices of the networks to facilitate the Layer 2 communication.
