netcf only reads/writes the ifcfg-* files in /etc/sysconfig/network-scripts, and knows nothing about the interface-specific routes in the route-* files. This is problematic, for example, when a script (or libvirt's virsh) attempts to move an existing interface onto a host bridge - everything about the physical device's configuration is moved over to the bridge, except for the route information which still (incorrectly) points to the physical device. netcf's XML should be enhanced to allow specifying multiple routes/gateways for each interface. This new XML will then need to be reflected in libvirt's parsing/formatting information for host interfaces.
This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux.

Red Hat invites you to ask your support representative to propose this request, if appropriate, in the next release of Red Hat Enterprise Linux.
There was insufficient time/resources to implement this feature in time for 7.2, moving to 7.3
There is no demand for this, and it is very unlikely to ever be implemented
