Lev,
Here are the outputs from the ip a and ip route commands. I have not enabled the route
yet. Eno1 was added after the ovirtmgmt was configured on the server. Sorry for not
having a lot of the information you need. This is new to us and were hoping the vendor
would figure the issue out, but it has been over 2 months. I will send the traceroute in
a couple of minutes.

Subject: Re: [ovirt-users] Creating a static route
Hi Doug,
In most cases it should not be required, especially as my guess (again it would be easier
if you could post the output of the "ip a" and "ip route") is that the
eno1 is part of the ovirtmgmt bridge.
What is the output of the "traceroute 172.22.20.31" that you get on the host
after you have added the static route?
Thanks in advance,

Lev,
One other question, since there are multiple enabled interfaces (ovirtmgmt and eno1), do I
need to specify an interface for the route add.

Subject: Re: [ovirt-users] Creating a static route
Hi Doug,
What do you mean by "static route is refused"?
What is the error message(s) you see?
Can you please try to add the route with the following command:
ip route add 172.22.20.31 via 172.21.12.61
If that doesn't work, then please provide more details, i.e. what is the exact error
message(s) you see, the version of your OS and oVirt, output of "ip a" and
"ip route" on your host(s), so that it will be easier to help you.
Thanks in advance,

Lev,
Thanks for your response.
If I attempt to manually add the route using route add:
route add -net 172.22.20.31 netmask 255.255.255.255 gw 172.21.12.61 dev ovirtmgmt
This static route is refused and all traffic is routed over the default gateway.
But if I use a server that doesn’t use the ovirtmgmt interface and set the same static
route, the required data is routed correctly over that static route.

Hi Doug,
What is the exact problem you are having while attempting to add a static route on the
hosts?
Thanks in advance,

Good Morning,
New to oVirt. We are using this with a backup solution from Commvault. The issue that we
are having is that we need to setup a static route for specific data between 2 remote
sites. The ovirtmgmt is configured with the correct IP and gateway for the server. We
need to route data over a different gateway so that we don't "max out" the
default network connection between the 2 sites. Example below
Ovirtmgmt IP - 172.21.5.31
Gateway IP - 172.21.0.250
We need any traffic with a destination of 172.22.20.31(Remote site) to route over this
gateway, 172.21.12.61
There are multiple servers in this configuration. Servers that are not using the
ovirtmgmt interface for their default, we are able to route the data. The only problem is
with attempting to setup a different static route on the ovirtmgmt interfaces.
Thanks in advance for any help!!!
Doug
