NLB & ESX 3.5

[daunce]

Hi,

Had a look around, and there's a few threads on this topic, but not any that answered my question.

I've set up 2 VM's on the same host using NLB with multicast, and having the usual problems of not being able to ping the nlb ip from outside of that subnet. From what i've read, i need to make changes on the switch, but as I dont have access to the switch, is it possible to make a change like this on the virtual switch within ESX?

I thought having a virtual switch, I could make these types of changes.

Any help appreciated.

You have to create a static arp entry, containing the multicast mac address and cluster IP, in what- ever L3+ device the cluster is using as next- hop or default gw.

That you can't do using a virtual switch...

Correct me if im wrong, but isnt this problem solved by setting the portgroup on the vswitch to "Notify Switches=No"
