John Marlin,

These days I keep hearing about switching over NETSH rather using ROUTE ADD.

Internally technically been replaced with NETSH?

Thanks for the info. We encountered the same problem on a Windows Server 2008 R2 (without Failover Clustering though) and this article provided us with the necessary clues.

Persistent routes were disappearing from the list of active routes when the DeleteIPAddress function was used (we're dynamically adding and removing an extra IP address at runtime).

One concern I have is that the interface ids apparently might change after a reboot, and I wonder what will happen with the persistent route in such a scenario.

Will the persistent route still be bound to the correct interface after the interface ids get renumbered for some reason?
