• The SNOs are deployed with SINGLE stack IPv6 only
• There a times when there are changes in the transport that require the SNO to be re-homed to a different transport - different IPv6 network and therefore address and default route
• The SNOs are deploying using IBI
• The requirement is to be able to update the IP address, subnet and gateway information on the SNOs MachineNet without having to redeploy
  • A stretch goal is to do this without having to reboot the SNO

In the snippet from the ClusterInstance, the bolded text is what would change.
