A design diagram shows tenant VXLAN tunnels for inter-subnet routing terminating only on the spines, while leaves bridge into L2 VNIs. Which architecture does that depict?
Select an answer to reveal the explanation.
Short Explanation
If only the spines finish the VXLAN/IRB for tenant routing, you are looking at CRB. Leaves bridge; spines route between subnets. ERB would show IRB on the leaves, and plain underlay or DCI stitching is a different picture.
Full Explanation
Recognizing CRB from placement: L2 VNI bridging on leaves with IRB/L3 VNI (tenant routing) termination centralized on spines matches Centrally-Routed Bridging. ERB would show VXLAN plus IRB on leaves. Underlay-only forwarding and DCI stitching describe other designs.
