Do you mean that you use the standalone fail_mode of an OVS bridge, i.e., with a rule of action "NORMAL" installed by default? > > Any simple solution for my problem ? > If the answer to my question above is yes, then you can simply achieve what you want by installing another rule preventing ingress udp traffic with source port 68 from the GRE port, with a higher priority than the default "NORMAL" one. This makes both networks not receiving DHCPDISCOVER messages from the other end, and so do the two DHCP servers. > Thanks > Deng Yao > -- regards, hunt _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
