I have a MS NLB cluster (Win 2003) which includes just two hosts. The cluster is configured to use Multicast operation mode (not IGMP).
For some reason I am seeing packets intended for the NLB cluster
Destination: MS-NLB-VirtServer-Multicast_bd:1a:0f:04 (03:ce:bd:1a:0f:04)
landing on all the servers on the LAN. Is it normal? Can something be done to get rid of them? We don't control the switch, but I could ask the guys to tweak it, if I knew what to ask
