Thanks Yongkun for your report. NoEncap mode support on Windows is indeed high priority. We're working on that but is blocked by an OVS issue: openvswitch/ovs-issues#197 Will address the issue soon with OVS team. |

Thanks @ruicao93 Do you have a rough estimation when it can be done? |

This PR implements support for Windows Noencap mode. It also includes flow optimization to improve Pod to Pod performance. Noencap: If same subnet, destination MAC in OVS is set with peer Node annotation. If not, host routing will be used to forward traffic. Hybrid: If same subnet, same as Noencap with same subnet. If not, same as Encap mode. The old PR antrea-io#1901 Fixed issue antrea-io#1632 Signed-off-by: Zhecheng Li <[email protected]>

Anything else you would like to add?
This gives the feature parity to Linux nodes. It will be useful for customers that don't like the performance penalty of an additional tunnel, as well as the MTU implication.
