Ops still floods all BUM traffic to every VTEP in a municipal VNI even when few leaves have interested receivers. Which improvement direction matches selective multicast concepts in EVPN?
Select an answer to reveal the explanation.
Short Explanation
If every VTEP still gets the whole BUM hose, the fabric is stuck on inclusive mode. Selective multicast (SMET-style) lets interested leaves raise their hands so quiet leaves stay dry. More Type-5 or killing IMET/IGMP does not magically shrink the flood set.
Full Explanation
Inclusive multicast delivers BUM to all VNI members; selective approaches advertise receiver interest so replication targets shrink to interested VTEPs when supported. Type-5 prefixes do not convert BUM into selective multicast. Removing Type-3 or disabling snooping typically worsens indiscriminate flooding rather than optimizing it.
