}
}

Solution

This is due to the usage of the protocol family. When the PPP over Ethernet over ATM LLC encapsulation type is used, you cannot configure the interface address. Instead, you need to configure the interface address on the PPP interface.

Do not configure the IP address on the interface at 1/0/0 , then if you try to commit the changes, it will be successful.
