Can there be more than 1 gateway to the same l2 network (say for HA) ? If gateway port G1 on chassis1 and gateway port G2 on chassis2, Then, when a VM a chassis3 sends a broadcast, it will tunnel to chassis1, and chassis2, and then get sent out of G1 and G2 to the same L2 network, ie, Can that broadcast packet get sent in duplicate to the physical network ? If so, would you have to run xSTP on the gateway ports ? _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
