[Dnsmasq-discuss] Support of labels in --interface

[Petr Mensik]

I think it is automatic if there is already IP from the same subnet on that interface.

$ ip a add 192.168.122.1/24 dev virbr0
# no secondary flag yet, first address of 192.168.122.0/24
$ ip a add 192.168.122.254/24 dev virbr0 label virbr0:1
# secondary flag present, it is second address of 192.168.122.0/24 on that device

Quick question from the lazy: how do you set the "secondary" flag on
the second address?

ip addr add <address> dev virbr0 label virbr0:1

doesn't seem to.

Dunno if it matters, just want to replicate this exactly........


Cheers,

Simon.
