When a CE6850HI, CE6850U-HI, CE6851HI, CE6860EI, CE7850EI, CE8850EI, or CE8860EI switch functions as a VXLAN Layer 3 gateway, configure a service loopback interface on the switch to loop back service packets of the VXLAN Layer 3 gateway.
Perform the following configurations:
<HUAWEI> system-view
[~HUAWEI] interface eth-trunk 1
[*HUAWEI-Eth-Trunk1] service type tunnel //Enable the service loopback function in the Eth-Trunk interface view.
[*HUAWEI-Eth-Trunk1] trunkport 10ge 1/0/1 //Add an idle member interface to the Eth-Trunk.
[*HUAWEI-Eth-Trunk1] commit
You can also find the answer in VXLAN Configuration Guide.
