BCF has a modular architecture that enables enterprises to avoid a “rip and replace” approach when introducing next-generation data center networking technology into their environments. BCF can be introduced in brownfield networking deployments through pods, enabling inter-pod communication through core routers and enabling BCF pods that are positioned across data centers to co-exist with legacy networks. This capability supports a granular and methodical approach to expanding the BCF footprint without impact to existing network infrastructure.

The following figure illustrates the addition of pods to an existing data center:
