Re: General questation about NLB Josh26 Aug 18, 2013 11:55 PM (in response to MarekGr) I'm trying to understand your concern.Are you suggesting you won't use Multicast NLB because you read 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 Check This Out

Such a mapping in an ARP reply is rejected by some routers so administrators must add a static ARP entry in the router mapping the Cluster IP Address to its MAC And if you don't yet follow Ivan, I urge you to do so! I can't make my mind up... #beer https://t.co/EEzYTdWjCz 2daysago Interesting... Nlb Unicast Vs Multicast Windows 2008 Also, unicast mode forces the physical switches on the LAN to broadcast all NLB cluster traffic to every machine on the LAN.

And i m using Workstation 9.Will it Work on workstation 9 ? Vmware Multicast Not Working and if this is the case, doesnt this affect network performance as the NLB traffic will be broadcast to all the ports? Reply Ioannis Theodoridis says: April 30, 2013 at 5:37 am My guess is you are probably still flooding your access switch if you don't put the static mac-address table entry. https://kb.vmware.com/kb/1006558 Thanks!!!

An important feature when the solution must be deployed in an unknown infrastructure: unknown switches or routers, physical servers or virtual servers, and the Cloud.Note that the solution is available on Windows, Nlb Multicast MULTICAST mode is by far the best one in my customer's case, and in most scenarios as well IMO.

Vmware Multicast Not Working

Re: General questation about NLB Josh26 Aug 11, 2013 6:33 PM (in response to MarekGr) It's a recurring question here.The short of it is that the caveats on Unicast NLB make http://communities.vmware.com/thread/111079?tstart=0 Thanks for pointing that out. Vmware Network Load Balancing Best Practice As you can see, ClientA sends the request to the Clusterd MAC Address, but that MAC Address is not in the switches MAC Address Table.  The switch acts as it should Nlb Unicast Vs Multicast TEST1 - NIC 1 for LAN IP 10.220.3.246 NIC 2 for NLB - 10.220.3.248 and CLUSTER 10.220.3.245 TEST2 - NIC1 for LAN IP 10.220.3.247 - NIC 2 for NLB - 10.220.3.248

I try in the the test vmware set the multicast . FYI - I started over again from the beginning I setup a new port group for the machines in the NLB cluster and removed the notify switch for the Port group Incapsula incident ID: 443000300123264198-302324895478120938 Request unsuccessful. The important thing to remember is to add the ARP and MAC addresses statically to the physical switch in order to forward the frames correctly.    Assuming my above example uses Nlb Not Working Vmware Multicast

Now, ClientA sends the same request to 1111.1111.1111 and gets a response from only 1 of the VMs.  This might make the network traffic more efficient, but also means that the Like Show 0 Likes (0) Actions 2.

No information provided here was reviewed by or endorsed by my employer or any other vendor or organization. if that makes any sense. Multicast allows inter-host communication because it adds a layer two multicast address to the cluster instead of changing it. This makes inter-host communication possible as the hosts retain their original unique MAC addresses and already have unique dedicated IP addresses.
