Monitoring
The GCP engineering team has implemented a fix to ensure route programming is propagating as expected. Following this fix we have observed a return to expected routing behavior. GCP and NetApp engineering teams continue to monitor the environment for stability.

Identified
In conjunction with GCP support an issue was identified related to route programming. In some cases routes in the SDN control plane were not being programmed into the forwarding plane. From a control plane perspective these routes were operational, and thus available for forwarding of traffic. When traffic was forwarded via one of these routes it would be black holed due to the missing programming in the forwarding plane.
