I think that the presence of two bridges in this configuration is a red herring. The way that packets make it from the GRE tunnel into the second bridge in this scenario is the same way that packets make it from a GRE tunnel into a bridge when there is only one bridge. If you are setting up a GRE tunnel with Open vSwitch for the first time, then it is probably easiest to just use one bridge (and keep the physical device off that bridge). _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
