PVE 8.2.2 default route goes missing after reboot.

[stv.Bundesadmin]

Just got a reply from Proxmox Support (Alexander), they're on it.
In the meantime, the workaround he provided is simple:

In /etc/network/interfaces, move
source /etc/network/interfaces.d/*
from the bottom up "above the vlan-interface where you define the gateway".

In my case, i placed it right below the sdn-bridge.

systemctl restart networking.service
now works properly, the default route doesn't vanish anymore.

thank you so much for the resolution. I would try now also.

I can confirmed that this is working! I moved it up all the way under here

auto lo
iface lo inet loopback

iface ens15f1 inet manual

iface enp131s0f0 inet manual

iface enp131s0f1 inet manual

iface ens15f0 inet manual

source /etc/network/interfaces.d/*

there is still some type of bug with this ... i need to do a 'ifreload -a' for the default route to be present.

my other servers with similar setup but using ovs vswitch don't have this issue.
