I have read and searched about the Multicast IGMP implementation of NLB with Windows 2003 but I am still confused?
I understand how Unicast NLB & the non-IGMP multicast works, along with the issues related to both. However I had assumed (wrongly it seems) that multicast with IGMP used real multicast IP addressing. I thought that the cluster application would be assigned a multicast IP address (how I expected this to work with the associated application I am not sure but hey ho I am a network engineer and try not to look beyond Layer-4
....).
Anyway I have searched and searched but can't seem to find a good description of how this works. In the help and online I keep finding the phrase
I am going to build a couple of VM guests and test this in the lab and verify the behavior with Wireshark, but if anyone has any good links I would appreciate it.
Thanks, Andy

However it doesn't appear this is actually configured anywhere.
