How to set network connection priority

[Mohammed Sadiq <sadiq sadiqpk org>]

Hi,

Is it possible to set IP routing (and DNS) priority when multiple
network is present?  Say like, “Connection A” to have lower priority
over every other connection, and “Connection B” having more priority
than “Connection A”, but less priority than every other connection.
So if there is ever a connection other than ‘A’ or ‘B’, that connection
will be used for IP (and DNS) routing, otherwise “Connection B” will be
used, and otherwise, “Connection A.”

I'm wring a C code (that will hopefully be into gnome-control-center),
so I would be okay with solutions that are possible via code only, or
just configuration changes for NMSetting.


Thanks,
Mohammed Sadiq
