How does an external load balancer identify all possible istio ingress gateways

When using an external load balancer, how does it identify which istio ingress gateway it can possibly hit i.e. I can manually access :/

  1. Is this manually configured or does the load balancer consume this info from an API
  2. Is there a recommended strategy for bypassing an external load balancer eg. roundrobin across a DNS which is aware of the node ip / port ?


Here’s a sample where i manually identify the node host / port
