QuestionQ33

Data Center Network Design

In an EVPN-VXLAN data center, why might you consider using discrete border leafs instead of assigning border roles to the spines?

  • A to provide for differentiated oversubscription ratios for traffic into and out of the data center
  • B to eliminate multicast traffic in and out of the fabric
  • C to allow for provisioning ACLs between the data center and the WAN
  • D to provide specific devices designed for handling traffic burstiness on the WAN
Explanation

Dedicated border leafs isolate external north-south connectivity from the spine fabric, allowing the capacity of data-center ingress and egress links to be independently sized. This supports differentiated oversubscription ratios for traffic entering and leaving the data center. In a leaf-spine VXLAN topology, spines primarily provide transit connectivity, while border leafs serve as the demarcation to external services and networks.
