Description

Steps to Reproduce:

  1. Create a new VLAN interface.
  2. Configure IPv4 Configuration Type as PPPoE.
  3. Configure IPv6 Configuration Type as DHCP6.
  4. Save and apply the changes.
  5. Navigate to Interfaces → GIFs and add a new GIF tunnel.
  6. Set the GIF Remote Address to the IPv6 address of the remote peer.
  7. For the GIF Tunnel Local Address, enter an IPv4 address (e.g., 192.168.101.1).
  8. For the GIF Tunnel Remote Address, enter an IPv4 address (e.g., 192.168.101.2).
  9. Save and apply the changes.
  10. Assign the GIF interface and enable it.
  11. Reboot the system. After reboot, the GIF interface remains down.
  12. To bring it back up, re-save the GIF interface configuration without making any changes.

The attached script addresses this issue.

It may be the regression of #3409

Hey Danilo,
Thanks for the script. It seems like the majority works (after a few edits by me), but when it comes to actually restarting the interfaces the last line (playback restartallwan) gives many errors with `route` and the result is that the gif0 interface is up, but it doesn't work.

I am using it over a PPPoE interface. What are my steps to debug this?

Tested on 25.07.1
Using the steps above, I was unable to create a GIF tunnel.
