What you expected to happen: All the ENIs attached to the worker nodes should have IP and gateway.
How to reproduce it (as minimally and precisely as possible):
Anything else we need to know?: Missing ENS IP causing to failed pods and no network connectivity in worker node. When i manually set the ip to ens6 and set the route , the pods started working.
