Configure OVH Bridge Network from command line

If you have a Proxmox or VmWare ESXi server on OVH network, you need to configure network interface once virtual machine is created.

First login to OVH, go to IP page. Find the IP address you need to assign to this new VM, create a Virtual MAC. OVH allow 2 type of MAC. If you are using Proxmox, use OVH Mac. For VMWare ESXi, use vmware vmac.

Once you have Virual Mac. you need to configure it in your VM network interface settings. For Vmware ESXi

Now login to Virtial Machine, run following commands

ip link set NETWORK_INTERFACE_HERE up
ip addr add FO_IP_HERE dev NETWORK_INTERFACE_HERE
ip route add GW_IP_HERE dev NETWORK_INTERFACE_HERE
ip route add default via GW_IP_HERE dev NETWORK_INTERFACE_HERE

In above, replace

NETWORK_INTERFACE_HERE = name of your network interface. This can be found with command “ip link”. Normally it is eth0 or ensXXX.

FO_IP_HERE = this is the Failover IP you will be using for this Virtual Machine.

GW_IP_HERE = This is gateway IP. For OVH network, it will be your servers MAIN IP address with last number replaced with 254.

Here is an actial example.

ip link set ens192 up
ip addr add 178.33.35.183 dev ens192
ip route add 149.202.199.254 dev ens192
ip route add default via 149.202.199.254 dev ens192

This settings will be lost when you reboot OS. For configuring network interface permanantly, you can do

• Configure Failover IP in Ubuntu 18.04 OVH VPS
• Debian 9/10 OVH Bridge Network Configuration
• Configure Networking in Fedora 28 OVH Proxmox
• OVH VPS Configure failover IP in Ubuntu
