ALB Teaming and multicast

Hello all,

I've a server with two "Intel(R) 82576 Gigabit Dual Port Server Network Connection".

For redundancy purpose I've decided to team together these interfaces.

I use TS reader to get a multicast flow but when the team is configured in ALB mode (with RLB disabled), the flow received is regularly lost

Do you have any idea of what can cause this ?

Thanks.

I saw that IGMP leave messages are sent regularly. On teaming documentation I saw that multicast traffic is always send on primary interface and when I set the "Load Balance Refresh Rate" parameter to 0, I don't have this problem.

Why the driver has to sent this leave ?
