A single network is sufficient to implement network load balancing, without the  prerequisite of two network cards and two IP networks as required by Microsoft NLB unicast mode.The virtual IP address configuration I would say for each port connecting to ESX's NICs participating in the NLB pool. Thanks for helping make community forums a great place.

One question of my own. Nlb Multicast Re: Windows 2008 R2 NLB is not working on Esxi 5.1 (Unicast & Muticast).. You Just Failed Your Private Cloud Project…Why?

we have a cluster with 6 ESX servers, 4 NIC each (wihin HP C3000 Blade enclosure) with DRS and HA enabled, so the NLB nodes can exists on any host.

If your switches do not support MULTICAST, you will have to setup Microsoft NLB in UNICAST mode. Share this:TwitterEmailPrintFacebookLike this:Like Loading... Because of they way NLB interacts with the network stack, and because VMware has virtualized the stack for their environment, you need to ensure you are following VMware's advice on configuring Windows 2012 R2 Nlb Setup Re: Windows 2008 R2 NLB is not working on Esxi 5.1 (Unicast & Muticast)..

If you have a two layer design (access-core) it's a bit different. The virtual IP address is set as an alias IP address on the NIC card of each physical or virtual machine. This functionality must be disabled on the Network Load Balancing interface for both DNS and Windows Internet Name Service (WINS); otherwise, each host’s computer name will be registered with the cluster IP this contact form Related About PiroNet Didier Pironet is an independent blogger and freelancer with +15 years of IT industry experience.

Same with additional layers (although that is not really optimal from the networking point of view).
