Microsoft 2008 R2 NLB Multicast - Accessing over subnets ?

Hi Microsoft NLB Gurus,

We have Microsoft 2008 R2 NLB multicast cluster running on VMware. And each host has single interface and we have a problem accessing the virtual IP over the subnet.
 
1. Adding static ARP entries would not be possible.
2. https://support.microsoft.com/en-us/kb/960916 is just for Windows 2008 not for WIndows 2008 R2
3. We do not want to go with Unicast at this stage

Forwarding enable will fix this issue ?

netsh interface ipv4 set interface "NLB NIC" forwarding=enabled 

Open in new window


But most of readings on the Internet recommends above command for the environment which has two interfaces and when NLB interface dose not have a gateway IP.

So, what would be the fix for this ?

In that case your options are limited and this is not going to work.

Multicast, must have Static ARP entries on ALL switches, uplinks in your organisation.

otherwise use Unicast.

Seek an alternate solution, how about Zen Load Balancer. (a VMware Appliance)
