[ovirt-users] Re: Creating a static route

Lev, I’m showing you the same outputs (ip a, ip route, traceroute, ip route add, and traceroute) from another server in this group that doesn’t use the ovirtmgmt for it’s default interface.

What is the output of the "traceroute 172.22.20.31" that you get on the host after you have added the static route?

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.

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.

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!!!
