I would like to restart this discussion as I am having trouble with configuration + performance. I would like send just tcp traffic via gre tunnel and would like to push a vlan tag before sending via gre tunnel. On receive side after gre decapsulation, match should happen on vlan_vid and configured actions executed. I don't think it is possible to do this in ovs currently based on what you had described earlier in another thread, but just want to check again if its indeed possible then how the flows should be configured on receive side.
On Tx side I have flows configured to match (gre_port = 2, eth_port = 1) dl_type=0x0800, nw_proto=6, nw_src=<src-ip>,nw-dst=<dst-ip>, actions=mod_vlan_vid:100,mod_vlan_pcp:4,2 dl_type=0x0800, nw_proto=47, nw_src=<src-ip>, nw-dst=<dst-ip>, actions=1 via tcpdump I see vlan packets encapsulated in gre header. on Rx side, I had configured dl_type=0x0800,nw_proto=47,nw_src=<dst-ip>, nw-dst=<src-ip>, actions=resubmit:2 in_port=2,dl_vlan_vid;100,dl_vlan_pcp:4,actions=strip_vlan,0 For packets coming in, first flow is matched for gre, second flow is never matched. If i change second flow to in_port=2,actions=strip_vlan,0 packets are matched but performance is bad. I am getting around 100Kbits/s on a 1G nic. If I understand correctly, part of the issue is that resubmit action is in userspace, but the bigger question is why first config on the Rx side doesn't work? Inputs appreciated.
