If I have pool, policy and irule in a same VIP, how will be the traffic flow, which of them evaluate first.

 ,

 

In F5 v11.4.0 and later, Policies are evaluated first before iRules.

 

Now if you have pool selection in LTM policy, then system will take actions w.r.t to pool specified in policy. Now if you have default pool as well as iRule configured on the same Virtual Server, then iRule will have high priority over default pool. If any traffic is not matching any condition in the iRule, traffic will be sent to Default Pool.

 

This is how F5 take actions.

 

Hope it helps!
