🎀 IFCFG-BRIDGE(5) — the ifcfg-ovs-bridge page, bestie 🎀

Okay so you're here because openvswitch bridges are a thing and you want your config to slay. This is the ifcfg-ovs-bridge situation. 💅

✨ NAME ✨

ifcfg-ovs-bridge — openvswitch bridge configuration.

🌸 SYNOPSIS 🌸

These config files live here:

/etc/sysconfig/network/ifcfg-*

💖 CONFIGURATION 💖

To set up an ovs bridge interface, you need a config file ifcfg-<interface-name> with the usual network settings. But bestie, you must add extra variables:

• OVS_BRIDGE <yes|no> — this one must be set to 'yes' to identify this interface as an ovs bridge interface.
• OVS_BRIDGE_PORT_DEVICE[suffix] <port device name> — this suffix variable contains the names of port devices to enslave into the bridge; each port suffix has to be a unique keyword, e.g. _1 .. _N.
• OVS_BRIDGE_VLAN_PARENT <parent device name> — permits to create a fake bridge referring to the parent bridge with implicit VLAN on the ports of the parent bridge.
• OVS_BRIDGE_VLAN_TAG <vlan tag> — the 802.1Q VLAN tag or ID used to filter traffic for the fake bridge on ports of the parent bridge.

🧪 EXAMPLE 🧪

Minimal example for a ovs bridge interface on eth2 and eth3, bridge interface itself configured via dhcp:

ifcfg-ovsbr0
     STARTMODE='nfsroot'
     BOOTPROTO='dhcp'
     OVS_BRIDGE='yes'
     OVS_BRIDGE_PORT_DEVICE_2='eth2'
     OVS_BRIDGE_PORT_DEVICE_3='eth3'

Note: STARTMODE='nfsroot' ®e.g. with ovs-vsctl. This start mode prevents the bridge from being teared down at system shutdown, which would cause all configuration saved in the openvswitch data base to be lost after rebooting the system. If no such local configuration is made, e.g. because the bridge is only used for ports being dynamically added by libvirt, other start modes can be used as well.
