Im trying to avoid flood switch in order to use NLB with 2 webservers(just one configured on NLB during the tests).
Even with a layer3 switch, with IGMP enabled, Im having flood.
- 1 webserver(win2003 SP2) on a layer3 switch
- the layer3 switch(3COM 3300) with a cable to another switch on our network
- multicast with IGMP enabled
- the VMAC added on the switch to the webserver port(the mac is automatically added if I turn on the IGMP learning)
I just hit F5 on browser and al lights on both switches starts to blink.
I tried 2NICs with unicast with the NIC wheres the LNB configured with a different subnet, still flood.
I read somewhere else to use a HUB, but I dont have one available.
What´s the correct thing to to here?
