Hello,

I created a loopback interface with the following commands:

sudo ip link add name ospf-lo type dummy
sudo ip link set ospf-lo up
sudo ip addr add 10.0.0.1/32 dev ospf-lo

How do I make this interface persistent? I am on Debian Trixie and using NetworkManager.

I tried the following but no success.

sudo touch /etc/network/interfaces.d/ospf.cf
sudo vim /etc/network/interfaces.d/ospf.cf

auto ospf

iface ospf inet static
  address 10.0.0.1
  netmask 255.255.255.255
