Hi,

Let's say we have three OS10 Switches at 10.5.x connected in a ring or meshed topology.

Only Layer 2 configurations, that is:

• the switches are running LACP connecting one another
• spanning tree is enabled
• a VLAN is configured across all the switches and the VLAN trunked allowed

Everything is working fine. The questions are these, for multicast:

1)  Can we configure more than 1 IGMP Querier for the VLAN for the topology? That is to say switch 1, 2 and 3 all will have the IGMP Querier configured in their VLAN configurations in the switches.

2) If it is supported, how does OS10 handled multiple IGMP Queriers on the network? What's the behaviour the switches adopt? Was there like a master elected and the remaining will be standby?

Thanks so much
