Maybe C and D make the most sense here. IRB interfaces are usually on the leaf switches to bridge between VXLAN and VLAN, so C fits. Also, traffic going directly over the VXLAN tunnel between leaf1 and Ieaf2 (D) sounds right since that’s how EVPN-VXLAN typically forwards East-West traffic in the fabric without involving spines in the data path. The spines usually handle control-plane or routing, not VXLAN termination, so options involving IRBs on spines (A) or VXLAN tunnels transiting spines (B) seem less likely.

Looks like the answer involves IRB interfaces on leafs, so C and D.
