[ovs-discuss] Anyway to bind eth5 to dhcp interface when eth5 got IP addr

[严超]

Hi, All:
        I configued my eth5 as dhcp interface but neutron default is
tapeb8c2d34-77.
        So I patched eth5 and tapeb8c2d34-77, but it doesn't work. eth5
receives dhcp request but not responding. Please help me out.
