Here we'll focus on IPv6-only apps. First iteration, IPv6 interface configuration. You can find the sample apps at:
One sample app (nc-create-config-ifmgr-32-ydk.py) configures a virtual interface (Loopback0) and second app (nc-create-config-ifmgr-36-ydk.py) configures a physical interface (GigabitEthernet0/0/0/0). In addition, you'll find boilerplate apps for interface configuration using the CRUD service.
Make sure you review the README file for how to use these apps. You'll find it at:
