Ops sees EVPN Type-2 MAC/IP routes on a city leaf but still claims the VXLAN MAC control plane is OSPF. Which correction is accurate?
Select an answer to reveal the explanation.
Short Explanation
Two phone books, two jobs: OSPF (or underlay BGP) gets packets to leaf loopbacks, and EVPN hands out the MAC/IP bindings for the overlay. An EVPN Type-2 is not an OSPF LSA with a costume on. If you see Type-2 routes, you are looking at the overlay control plane doing its real work.
Full Explanation
IP fabric underlays use routing—often EBGP/IBGP or an IGP—so VTEP addresses are reachable across leaf-spine. Separately, EVPN over MP-BGP distributes MAC/IP (Type-2) and other overlay routes that populate VXLAN forwarding. Conflating OSPF LSAs with EVPN route types is a common misconception. Presence of EVPN Type-2 routes indicates overlay MAC/IP signaling, not the absence of underlay IP routing. Both layers must be healthy for end-to-end tenant connectivity.
