Hello,
I am connected to physical devices.
I have created a template based service.
When i try to create a service instance , it says it is created as shown below. but there is no config change on the router side.
May you point me to a direction for troubleshoot this case or tell me a method to debug ?
Many thanks in advance.
below : yang model, template and screen output while creating the service
note: i have not yet implemented spoke part of the yang file into the template
