Problem loading configuration after reboot VyOS 1.2.0 in bare metal deployment

Bugs

1

I’m using VyOS now for an L2TPv3 tunnel between two remote sites at work.
The first router (VM under ESXi 6.5) works perfectly.
The second router, which has been installed on a PC, can’t get to load the full configuration after reboot (the part lacking is the L2TPv3 configuration). They both have the same version.
Strangely, when I issue “load”, the router gets the full configuration loaded and asks for commit! So I guess the configuration file is OK. Yet VyOS can’t load it properly after reboot.
I tried to reinstall but I had exactly the same issue. My Hardware is a Dell OptiPlex 3050. (I don’t have other machines to test on).

Version is :

vyos@vyos:~$ sh ver

Does anyone know how to debug or eventually tweak the way VyOS saves/loads its configuration ? is this a known issue ?

Can you share your config please?

Of course :slight_smile:

can you please do it via ‘show config comm’. Easier to copy and test.

I think you don’t have an IP address by the time l2tp is supposed to start. Can you try it with static IPs?

Bingo! that should be it! I just used a static ip address and everything worked fine!
By the way I should have thought of this. Thanks a lot for your help!!
