Description of problem:

Reading Fedora Networking Guide and other pieces of official documentation, there is no description of a scenario in which a box is connected to the Internet via *multiple* connections (multiple providers?) and a completely *automatic* failover between these connections is sought.

Please see:

http://docs.fedoraproject.org/en-US/Fedora/22/html/Networking_Guide/ch-Configure_Networking.html


Version-Release number of selected component (if applicable):

Fedora 22 Networking Guide Edition 1.0, as of June 9th, 2015.


Actual results:

There is no official documentation about automatical failover between multiple Internet connections, using NetworkManager or not.

Expected results:

Such official documentation should exist, for both Fedora and Red Hat Enterprise Linux (especially regarding the scenario in which the Fedora box is used as an Internet gateway/router, which is very common... almost a FAQ...).
