Hello,

I have a box with multiple network interfaces.  I am running:

# uname -a
Linux rhino 5.2.11-200.fc30.x86_64 #1 SMP Thu Aug 29 12:43:20 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

# cat /etc/*release
Fedora release 30 (Thirty)
NAME=Fedora
VERSION="30.20190905.0 (CoreOS preview)"
ID=fedora
VERSION_ID=30
VERSION_CODENAME=""
PLATFORM_ID="platform:f30"
PRETTY_NAME="Fedora 30.20190905.0 (CoreOS preview)"


I am happy with eth0 as it uses DHCP.

What is the best way to configure on the system the below command:

$ sudo ifconfig eth1 0

I have a container in which I have an interface - call it a OVS bridge which will be linked to eth1 and that interface will get the IP address.  I also need to force the container to use eth1 as the default route interface and not eth0.

I understand that Network Manager (/var/run/NetworkManager/) is the method to configure networking on this CoreOS.  Is this model supported?  Any references to how this can be accomplished?

I have another similar use case for a VPN tunnel.

Appreciate pointers.

Thanks & Regards
