In a conductor based set up, there is a need to migrate Internet link in one of the stores from PPPoE based to normal Ethernet link with public IP. However after completing the activity the newly created Internet L3 Link is showing admin down.
The following sequence was followed for migrating the ISP from PPPoE to L3 Internet Interface.
Create new Internet L3 Interface
Delete PPPoE Interface
Modify the service routes from PPPoE to newly created Internet L3 interface.
Validate and commit the configuration.
However the Admin Status after the change is down. Even though the config validation and commit was successful.
Instead of committing the configuration in one go, which includes both creation of new INTERNET L3 interface and deletion of exiting interface PPPoE interface split them as below
Delete PPPoE Interface and validate and commit
Create new Internet L3 Interface and validate and commit
After which the the newly created INTERNET interface was successfully provisioned and admin status was operational and UP.
