When you say your LB method is Topology, have you assigned that to the WideIP or the pool itself? If you assign it to the WideIP then the WideIP will use the topology records to choose a pool not a VS within the pool. If you assign the method of topology to your pool then the topology records will then be used to choose a VS from within the pool.

    Hi Brad, Yes, the LB method = Topology was assigned to the WideIP. While the pool itself was assigned , LB = Round Robin. I am also curious here about the topology thingy, what about if we have multiple WideIP, with multiples topology, how does the GTM decide which topology to be used for the respective WideIP's? Bcoz from my logic view, all the topology records is like a global attributes and does not associate with the WideIP.
