Describe the bug

After restarting the DUT, IPoE subscribers get re-established whereas PPPoE/L2TP subscribers do not.

To Reproduce

Bring up IPoE/PPoE/PPPoE over L2TP subscribers. Restart the BNG. Check if IPoE/PPoE/PPPoE over L2TP subscribers get re-established back again

Steps to reproduce the behavior:

  1. Bring up IPoE/PPoE/PPPoE over L2TP subscribers.
  2. Restart the BNG.
  3. Check if IPoE/PPoE/PPPoE over L2TP subscribers get re-established back again

Expected behavior

All IPoE/PPPoE/PPPoE over L2TP should all get re-established back again.
