A township enables IGMP snooping on EVPN-VXLAN tenant bridges. How should that state relate to EVPN multicast signaling?
Select an answer to reveal the explanation.
Short Explanation
IGMP snooping is the local ear at the leaf—who on this switch asked for the group—while EVPN carries that interest across the fabric. They team up; snooping does not fire EVPN or live only in OSPF. And it should not blow DF rules for multihoming.
Full Explanation
IGMP/MLD snooping builds local receiver state on the VTEP/bridge. EVPN multicast features can propagate or act on that interest for optimized overlay distribution. Snooping does not obsolete Type-3/SMET signaling, is not an underlay-OSPF-only feature, and must still respect multihoming/DF rules for delivery into an ES.
