Windows NLB - Multicast

-

hi,

 i configured windows nlb in multicast mode , gave mac network team adding static arp entry in switches, wondering whether mac id dynamic or stay same untill change mode, or should go igmp mode

they stay same:

"network load balancing provides second mode distributing incoming network traffic cluster hosts. called multicast mode, mode assigns layer 2 multicast address cluster adapter instead of changing adapter's station address. the multicast mac address set to 03-bf-1-2-3-4 for cluster's primary ip address of 1.2.3.4. since each cluster host retains unique station address, mode alleviates need second network adapter communication between cluster hosts, , removes performance penalty use of dedicated ip addresses."
