I am not able to delete the default gateway from my debian 11 server:-
peter@discovery:~$ sudo route -n

and then also:-
peter@discovery:~$ sudo ip route del default via 192.168.1.13
peter@discovery:~$ sudo route -n

The default gateway 192.168.1.13 is being very stubborn and doesn't want to go. How do I get rid of it please. I have a Debian 11 Bullseye server.
Many thanks
Just to add this is the /etc/network/interfaces file:-
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
