Symptoms
In a cluster with GRE configured over a Cluster Virtual IP:
GRE traffic fails to pass after all cluster members are rebooted at the same time.
Traffic capture shows that GRE traffic uses the IP address of a physical cluster interface instead of the Cluster Virtual IP to encapsulate the traffic.
Cause
While the cluster members reboot, the Cluster Virtual IP address is not available.
