I have a /28 network and I’d like to add a single IP (/32 network). On my Debian machine this looks like:
auto eth0
iface eth0 inet static
address 192.0.2.212/28
gateway 192.0.2.209
iface eth0 inet static
address 192.0.2.175/32
Then, on the router (192.0.2.209/28) I have a static route: “route 192.0.2.175/32 next-hop 192.0.2.212”
Is there anything wrong with this approach ?
