A leaf needs to discover other VTEPs participating in a city VNI so BUM traffic has destinations. Which EVPN route type primarily supports that inclusive multicast / IMET membership role?
Select an answer to reveal the explanation.
Short Explanation
When a leaf needs the guest list for a VNI's BUM party, Type-3 IMET is the RSVP. It says "I am in this VNI—send me floods." Type-5 is about prefixes, Type-2 about hosts, and Type-4 about the Ethernet segment—not the inclusive multicast roll call.
Full Explanation
Type-3 IMET advertisements let VTEPs learn which remote VTEPs belong to a VNI for inclusive BUM distribution (commonly ingress replication). Type-5 carries IP prefixes for L3 EVPN use cases. Type-2 advertises MAC(/IP) hosts rather than VNI multicast membership. Type-4 Ethernet Segment routes support multihomed ES discovery and DF context, not IMET replacement.
