Loadbalancing Virtual Server as Nodes

Hello f5_rock.

Thanks for your answer!

As I read here VIP-targeting-VIP is not possible using Loadbalancing resolution (Configuring several Local VS as members of a pool). The only way is to configure an iRule with a command called virtual.

https://support.f5.com/csp/article/K10379

I have tried to use this command inside the LB_SELECTED event, but it's not working at all 😞

when LB_SELECTED {
    virtual mytestingVS
}

Using this command in a previous event is unuseful for me, because I'm losing the point of LB selection.

By the way, my final goal is to configure Active-Passive Loadbalancing between two cluster (2 nodes by cluster) with no preempt

Cluster1 (Node1, Node2) with Round Robin
Cluster2 (node3, Node4) with Round Robin

Each cluster is loadbalanced using active-passive but I need to avoid peempt (no switch back to active cluster after recovering).

Any help would be appreciated

KR, Dario.

Great!

 

I have recently detected that the expression "VIP-targeting-VIP is not possible using Loadbalancing resolution" in my last comment is not true 🙂

 

To do so, it's necessary to use the expression "

LB::reselect

virtual {VS_name}

 

when LB_SELECTED {
    if { [LB::server addr] eq '10.1.1.1' } {
        LB::reselect virtual vs-local-traffic-handler
    }
}
