Routing Strategy for a Tenant Based Data Center Environment
With so much emphasis on security in the current networking world, Data Centers have started to diverge from traditional flat Layer 2 networks and move toward a more secure, segregated architecture of routing and switching. This new architecture takes advantage of some of the same network principles that have been implemented throughout the rest of the Enterprise Network as a strategy to segment Customer Service Representatives from the rest of the users as a requirement of the Payment Card Industry (PCI) standards. This strategy relies heavily on leveraging existing Multiprotocol Label Switching (MPLS) networks using Virtual Routing and Forwarding (VRF) instances. These VRFs are essentially Virtual Local Area Networks (VLANs) for the Layer 3 routing world which allow for separate, unique routing tables within the same router. The objective of this project is to provide Junior Engineers in Network organizations the foundation for learning to build, troubleshoot, and support the new Data Center networks.
