City engineers see EVPN Type-2 routes for a server MAC and IP on the municipal leaf fabric. What is the primary purpose of those Type-2 advertisements?
Select an answer to reveal the explanation.
Short Explanation
Think of Type-2 as the fabric's host phone book: which leaf owns this MAC—and often which IP rides with it. City servers show up there so remote VTEPs can unicast without guessing. It is not the underlay map and not the BUM roll call.
Full Explanation
EVPN Type-2 (MAC/IP Advertisement) routes publish end-host MAC reachability and may include the host IP for integrated routing and bridging and ARP/ND suppression. Underlay Clos ECMP uses IP fabric routing, not Type-2. Ethernet Segment and DF roles lean on Type-1/Type-4, while inclusive multicast membership is Type-3 (IMET).
