Red Hat Bugzilla – Bug 1005416
NM should treat routes differently depending on their origin
Last modified: 2014-06-17 22:48:31 EDT
This is a bug for tracking the implementation of a new functionality in NetworkManager. Currently, NM treads all routes the same, regardless how they were configured. Routes should be tagged internally in NM depending on their origin (e.g. DHCP, RA, static, ...). One use of this is for example in bug #999544. Currently NM considers the activation of a connection as failed, when a route cannot be set. This makes mostly sense for manually configured routes, because a partial failure of setting a route cannot be displayed to clients. This behaviour might be undesired for routes from DHCP because a wrong configured route on the DHCP server could make the connection unusable.
Over to you thomas; I'll try to merge dcbw/vpn-no-iface this week to provide the basis for your work here. Thanks!
