Hi,
If no configure of "datapath-id" in other_config of br, then it will
choose the minimum non-local MAC address among all of the ports in bridge. The
relevant code is in the find_local_hw_addr
function（https://github.com/openvswitch/ovs/blob/master/vswitchd/bridge.c#L2322）.
ing "unknow" address for the lsp of
l2gw, to direct all traffic from logical switch to VLAN network. I had spent
much time to find this problem, other people will meet it ethier.

To tune the election timer for raft on say nb db, you can tune with below
