The city prefers anycast IRB default gateways on every leaf so spines mainly forward underlay transit. Which EVPN architecture matches that preference?
Select an answer to reveal the explanation.
Short Explanation
ERB puts the front door (anycast gateway) right on each leaf so traffic can route at the edge. Spines stay mostly underlay transit. CRB would drag those gateways back to the spines.
Full Explanation
Edge-Routed Bridging distributes IRB/default-gateway and typically L3 VNI routing to the leaf VTEPs, leaving spines primarily as IP underlay transit. Anycast gateways on leaves are the classic ERB pattern. CRB centralizes IRB on spines/border; STP-only or MPLS L3VPN without VXLAN are different architectures.
