Two servers attached to different city leaf VTEPs share the same subnet and VNI. How should east-west traffic between them behave in the VXLAN data plane?
Select an answer to reveal the explanation.
Short Explanation
Same subnet, same VNI—picture two desks on the same open floor even though they sit in different buildings. VXLAN just stretches that floor across the city’s leaf-spine trucks. The packet gets wrapped, driven across the underlay, unwrapped, and bridged—no IRB detour required for that east-west hop.
Full Explanation
Same-subnet communication across VTEPs uses the L2 VXLAN overlay for the shared VNI. The ingress VTEP encapsulates the Ethernet frame toward the remote VTEP; the egress VTEP decapsulates and bridges locally within the mapped bridge domain. IRB and an L3 VNI are used when hosts are in different subnets and need overlay routing, not for ordinary same-VNI bridging. Underlay devices forward outer IP packets and do not need to terminate tenant L2 for this path.
