Loadbalancing Virtual Server as Nodes

Hello.   I'm trying to configure a complex solution of loadbalancing.   One part of this solution needs to loadbalance virtual servers which reside in the same F5.   VS1 -> Pool1 -> Member1,...

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.
