ratio-least-connections-member doesn't work as expected

Well, I labbed out your situation and I have the same issue. It seems as if "least connections" takes precedence over "ratio".

 

As soon as I changed my LB method to "Ratio (member)" the LB acted properly and heeded my ratios.

 

As soon as I change it back to "Ratio Least Connections (Member)" it goes back to 50/50 between my two vips.

 

My only advice would be to change your LB method to just "Ratio (member)"

 

(my lab version was 13.1.1.3)

Thanks Dylan!

 

"Ratio (member)" works.

 

For "Ratio Least Connection (Member)" mode, my understanding is "ratio" should take precedence over "least connections", but obviously it isn't. I'm wondering if this is a bug in V13. Not sure if other versions having this problem.
