I have two VMs on Hyper-V2012 running windows server 2012 R2, add NLB adapter for both VMs and enable Mac address spoofing, create NLB cluster with mode multicast, failed to ping from other VLAN. After change cluster mode to unicast, able to ping from
other VLAN, but our design need multicast mode, what's the problem, do we need configure static ARP on switch? Thanks & Regards!
