Need help with round_robin and gateway connected clusters

Hi,

I am struggling to implement ROUND_ROBIN in gateway connected clusters. Can you help?

  • I’ve just been through the gateway connected clusters turorial https://istio.io/docs/setup/kubernetes/install/multicluster/gateways/
  • All the traffic from foo to bar is going through cluster2 gateway over mtls .
  • Sadly when you have multiple pod in the bar deployment, the gateway does not loadbalance traffic properly between the bar pods.
  • Instead, the gateway seem to prefer reusing the same connections and always send the traffic to the same bar pod. they arrive to bar pods by batch

anything i am doing wrong? thx
