why walk on packet l2tp connection when not connected?

Hello!
Please tell me, is it correct that the router L2tp roll shows packet movement all the time? If you don’t have a l2tp connection, you don’t have to? Is the roll in the wrong order in the configuration? Maybe you need something extra?
My configs below …
Thank you.
