Win NLB with IGMP snooping on HP c7000 GB2EC switch?

Anyone done that?

- If I enable IGMP snooping on the switch, then the traffic to the NLB
address is dropped completely
- If I disable IGMP snooping on the switch, then the traffic to the NLB
address floods to all ports (as expected).

Seems to be an issue with MS using non-class-D IP addresses.

Can't add static arp entry on swtich for multicast MAC address.

(I also posted to 'microsoft.public.applicationcenter.nlb', but that group
looks pretty dead, will remove message from that group).


Thanks.
