A fabric diagram shows VXLAN VTEPs and IRB interfaces on every leaf for tenant default gateways. Which EVPN architecture does that map to?
Select an answer to reveal the explanation.
Short Explanation
IRB on every leaf is the ERB tell — gateways live at the edge next to the servers. CRB would keep those IRBs up on the spines. STP roots or bridge-only fabrics are not that picture.
Full Explanation
Edge-Routed Bridging is identified by VTEP plus IRB (and typically L3 VNI) functions on leaf switches that host anycast or distributed gateways. CRB centralizes those IRBs; STP-rooted L2 and MAC-VRF-only bridging without leaf IRB do not match the diagram.
