I tested with linux-4.4 but it didn't work. "tcpdump -vv -ni lo" shows VXLAN packets are sent but they seem to be lost somewhere. To support the use case [2], destination needs to be determined by VNI and (outer) destination IP address. The older vxlan_rcv() seems to use destination addresses in IP headers, but the newer version doesn't seem to do that. > Thank you, > Jakub > > >> Jakub > >> > >> [1] > >> https://github.com/openvswitch/ovs/commit/e23775f20e1a4c193c22f3fc78fb41ebcd93eeac > >> [2] http://paste.fedoraproject.org/391442/68587331/ > >> _______________________________________________ > >> discuss mailing list > >> discuss@openvswitch.org > >> http://openvswitch.org/mailman/listinfo/discuss > > _______________________________________________ > discuss mailing list > discuss@openvswitch.org > http://openvswitch.org/mailman/listinfo/discuss _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
