Hi All, We are trying to get MPLS push/pop operations working with kernel support using openvswitch devel/mpls-v2.52 branch but having issues. please find the detailed description below and let us know if we are missing anything. We tried various combinations of --protocols=XX and --flow-format=YY, where XX= OpenFlow13,OpenFlow12, OpenFlow11 and YY = OXM-OpenFlow13 and OXM-OpenFlow12 as described at http://openvswitch.org/cgi-bin/ovsman.cgi?page=utilities/ovs-ofctl.8 with no luck. At the same time, we had NO issues with userspace implementation of the switch.
So my question are. 1. Are MPLS push/pop operations known to work with devel/mpls-v2.52 kernel support ? 2. If no, is there any other branch I should try ? 3. If yes, what's wrong with our configuration. And If someone has a working configuration, can you please post ? Description: ======== openvswitch branch: devel/mpls-v2.52 kernel version: 3.8.0-29-generic #42~precise1-Ubuntu SMP Wed Aug 14 16:19:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux OpenFlow Protocol version tried: OpenFlow11, OpenFlow12, OpenFlow13. configuration used: sudo ovs-vsctl add-br br0 sudo ovs-vsctl set bridge br0 protocols=OpenFlow10,OpenFlow11,OpenFlow12,OpenFlow13 sudo ovs-vsctl add-port br0 eth0 sudo ovs-vsctl add-port br0 eth1 sudo ovs-ofctl --protocols=OpenFlow13 --flow-format=OXM-OpenFlow13 add-flow br0 in_port=2,actions=mod_dl_src=00:0c:29:2b:9c:82,mod_dl_dst=00:0c:29:08:4d:d0,push_mpls:0x8847,set_field:100-\>mpls_label,output:1 sudo ovs-ofctl add-flow br0 in_port=1,dl_type=0x8847,actions=mod_dl_src=00:0c:29:2b:9c:8c,mod_dl_dst=00:0c:29:44:86:6c,pop_mpls:0x800,output:2 As mentioned above the same configuration work well with openvswitch userspace implementation. thanks for your help, Regards Raghu.
