Title: Is there a way to specify backup for Cluster endpoints.

Description: I am new to Envoy. How do i treat some endpoints as a backup and envoy forwards no ingress traffic to these servers unless all other endpoints that are not marked as “backup” fail the health check.

You're probably looking for priority levels https://www.envoyproxy.io/docs/envoy/latest/intro/arch_overview/upstream/load_balancing/priority?

How do i configure Priority levels so that the traffic goes to P1 only when all the nodes under P0 becomes unhealthy. I think currently the traffic sent to both P0 and P1 based on the number of healthy nodes under P0 ?
