tcpdump works on Linux network devices whether they have an IP address configured or not, so that isn't the problem. Do you want to do switching or routing between the two interfaces? OVS is a switch, not a router, so if you want to do routing, then OVS is not the obvious choice, although it might usefully be a component of a solution. If you do want to do switching, then the Linux routing table is not relevant. If you want to set up a switch named br0 with interfaces eth0 and eth1, then starting from a clean setup you can run: ovs-vsctl add-br br0 ovs-vsctl add-port br0 eth0 ovs-vsctl add-port br0 eth1 You haven't really said what setup you are currently using, unless I missed it somewhere. It sort of sounds like you have two separate bridges, one of which contains one Ethernet interface and the other of which contains the other. That setup only makes sense if you are doing routing or tunneling or something else to span between one bridge and the other. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss_openvswitch.org
