Nginx Plus LB as backend node member on F5 LTM

Give this a try (assuming the port in your pool), make sure you select the LB algorithm to ratio (member):

tmsh create ltm pool my_pool_name \
    members add { 10.10.20.5:443 { ratio 4 } 10.10.30.5:443 { ratio 1 } }

To configure F5 LTM for traffic load balancing with your specific requirements (80% traffic to Azure VM and 20% to AKS via Nginx Plus), you can use iRule or Traffic Segmentation based on weights in F5 LTM. Here’s a short configuration outline:

1. Create Pool and Add Members:
   • Pool 1: Create a pool with two members:
     • Node 1: Azure VM (10.10.20.5)
     • Node 2: Nginx Plus virtual server (10.10.30.5)
2. Assign Weights:
   • Set weight for Node 1 (Azure VM) to 80.
   • Set weight for Node 2 (Nginx Plus) to 20.
3. VIP Configuration:
   • Configure F5 LTM VIP (10.10.10.10) with the relevant pool as the backend.
4. Traffic Distribution:
   • F5 LTM will now distribute 80% of traffic to the Azure VM (Node 1) and 20% to Nginx Plus (Node 2) based on the weight configuration.

This setup will ensure traffic is distributed according to the required percentages.
