I recently upgraded my lab vCenter to the vCenter Server Appliance (VCSA) v6.5.

As I need a static route on my network, I went to add that in the same way that I’ve done for other VCSAs, only to find that the networking has changed.

VCSA 6.5 now uses systemd-networkd to control networking. Any attempt to use “service network restart” will generate a bunch of error messages about “exiting with error 6”. Editing files in /etc/sysconfig/network  will have no discernable effect.

So how do you add a static route under the new networking regime?

Log on to your VCSA using ssh (or the console) and start a shell.

cd /etc/systemd/network

There you will find all the network config files.

Typically you will have just one, named “10-eth0.network”.

The contents of this file are relatively self explanatory:


Add a new section at the bottom of the file using your favourite text editor:


Again, the format for this is pretty obvious.
Once that’s saved, run:

systemctl restart systemd-networkd

Check that your route has taken using

root@vc01 [ ~ ]# ip route show
default via dev eth0  proto static dev eth0  proto kernel  scope link  src via dev eth0  proto static
