Hello,

 

Below are configuration examples.

 

  1. Ratio (Member) -Here you simply define ratio to each member under pool. And this ratio will be specific to this pool only.

 

 

2. Ratio (Node) - Here while creating node, you need to define ratio to the node. Default assigned value is 1.

Once you define ratio to the node. You can call those node under pool. If under pool, Ratio (Node) algorithm is configured, then F5 will distribute requests according to weight configured on node level.

 

 

3. Ratio (Session) - This requires L4 and L7 profiles. F5 monitor pending and active sessions. And then calculates the weight.

 

Hope it helps!
