Explanation
IGMP Snooping (Internet Group Management Protocol Snooping) is the correct AHV feature for this use case. It works at Layer 2 by monitoring IGMP membership report traffic between VMs and their default gateways. The virtual switch (Open vSwitch in AHV) uses this information to build a forwarding table so multicast packets are only sent to ports connected to VMs that have joined the multicast group, preventing unnecessary flooding to all VMs. LACP (A) is for link aggregation bonding. UDP (B) is a transport protocol, not a traffic optimization feature. Network Segmentation (D) isolates traffic but does not selectively forward multicast based on group membership.
