A city design needs to advertise an Ethernet Segment Identifier so multihomed leaves can discover the shared ES and participate in DF election. Which EVPN route type serves that high-level purpose?
Select an answer to reveal the explanation.
Short Explanation
Need to announce "these leaves share this ESI"? That is Type-4 Ethernet Segment territory—the handshake for multihomed ES discovery and DF election context. Type-5 is prefixes, Type-2 is hosts, and Type-3 is VNI BUM membership—not the ESI roll call.
Full Explanation
Type-4 Ethernet Segment routes advertise ESI information so PE/VTEPs attached to the same multihomed segment can discover each other and run Designated Forwarder election. Type-5 advertises IP prefixes. Type-2 advertises MAC(/IP). Type-3 IMET signals inclusive multicast membership for a VNI rather than electing the DF for an ESI.
