In the city lab, engineers observe EVPN Type-2 routes both with and without an IP address. What conceptual distinction do those variants represent?
Select an answer to reveal the explanation.
Short Explanation
Type-2 can be just the MAC name tag or the MAC-plus-IP combo plate. The IP-inclusive flavor feeds IRB and ARP/ND suppression so the fabric answers "who has this IP?" without flooding every leaf. Neither form is underlay loopback glue.
Full Explanation
RFC 7432-style MAC/IP Advertisement routes may carry a MAC alone or MAC with host IP. MAC+IP enables integrated bridging/routing behaviors and ARP/ND suppression caches on remote VTEPs. MAC-only ads remain valid for L2 reachability. These are overlay host routes, not underlay loopback exchange, and are not Type-5 prefixes.
