Hello team,

Is it planned to allow more than one loopback ?

it will be very useful, in the case if you want to separate the underlay with overlay for example.

thank a lot.

Hi
You can use dummy interface.
It's like a loopback interface.

If you want multiple interfaces with the same properties as the loopback, use dummy interfaces.

set interfaces dummy dum0 address 192.0.2.1/24
set interfaces dummy dum1 address 203.0.113.1/24

For historical reasons, the Linux kernel supports only one loopback, and changing it would break some things, so the kind of loopback that is not limited to just one interface was called dummy.
