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.
Version-Release number of selected component (if applicable):
Fedora 22 Networking Guide Edition 1.0, as of June 9th, 2015.
There is no official documentation about automatical failover between multiple Internet connections, using NetworkManager or not.
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...).
Thank you for raising this bug.
I'm closing this bug as part of a Bugzilla cleanup effort. The most likely reason is that the bug has been opened either against a component we no longer publish, or against Release Notes for an EOL release.
