No default route on device restart unless interface manually reloaded?

[HardTack5]

I have a PPPoE interface that runs on a VLAN, I find after a restart I do not have internet connectivity from the LAN network as the gateway is not selected as the default route.

Once I manually reload the PPPoE interface it then enters the route table internet reachability from the LAN is restored.

Is there some config change I can make to avoid this?
