The SLB bonding implemented by Open vSwitch is indeed active/active. Please explain why you think that it is active/passive. Also, Open vSwitch 0.99.2 is from February. The latest release is 1.1.0-pre1, and 1.1.0-pre2 will be out soon. > I've redundant physical switching for the bond networks, but without > spanning tree support (HP 1810G), therefore no inter switch links.

With Open vSwitch bonding, you plug both (or all) of the bonded ports into the same switch. It's not a way to obtain redundant switching. If you want to use another form of bonding, you can use OVS with Linux bonding. Linux supports multiple forms of bonding. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss_openvswitch.org
