Example is:

LB_FAILED Trigger points:

 

  1. When failed to select a pool member
  2. When Pool member selected is not reachable from F5
  3. When Pool member fails to respond to connection

When LB_Failed trigger happens request will go to Test1 if a server dies in the middle of an active connection, and send clients to Test2 if there are no active pool members to load balance.

 

hope this clears.
