Hi, Thanks. But I am still confused by section Logical_Router TABLE in http://www.openvswitch.org/support/dist-docs/ovn-nb.5.html

It tells that
       load_balancer: set of Load_Balancers
              Load  balance  a  virtual ip address to a set of logical port ip
              addresses. Load balancer rules only work on the Gateway routers.

You can associate a load balancer to a distrubuted logical router.

If you want to load balance a floating ip/external ip to OVN internal IPs, then the distributed router should have a gateway router port so that DNAT on the LB VIP is done on the gateway chassis which has claimed the gateway router port.
