L2TP with external radius, accouting issues

Hi,

Why L2TP server sends accounting On/Off and not Account Start/Stop, when L2TP session begin and end?

Can anyone help me?

Thanks

please give me Link to configure L2TP Server on Mikrotik from Winbox.

Thank You

The configuration is very simple as any ppp connection in the routeros.
