A dual-homed application pair at the water utility uses ESI multihoming with anycast VTEP behavior. At a high level, what does that change in the VXLAN data plane?
Select an answer to reveal the explanation.
Short Explanation
Multihoming with anycast/ESI is like two loading docks sharing one city address for deliveries. Remote leaves steer encapsulated frames toward that shared outer destination rather than picking a random single-homed VTEP. The overlay still uses VXLAN—you’re just choosing the right front door.
Full Explanation
Ethernet Segment Identifier (ESI) multihoming and anycast VTEP constructs let remote VTEPs send encapsulated traffic toward a shared next-hop/VTEP address representing the multihomed segment. That choice affects outer destination selection in the data plane while still using VXLAN encapsulation. It does not eliminate underlay addressing or replace VNIs with QinQ. Understanding this next-hop behavior helps utility operators predict how flows land on dual-homed leaves.
