Doc Text:
There is a known issue that OVN load balancer does not open new connections while fetching data from members. Instead, the load balancer modifies destination address and destination port and sends request packets to the member. As a result, you cannot define IPv6 members if you use IPv4 load balancer addresses, and you cannot define IPv4 members if you use IPv5 load balancer addresses. There is currently no workaround for this issue.

Hello Alex,

This issue is 'Known Issue'. It has never worked for OVN Load Balancer. We are going to fix this case in future.
