Networking/Bridging

The printable version is no longer supported and may have rendering errors. Please update your browser bookmarks and please use the default browser print function instead.

Using iproute2 (runtime only)

Example configuration:

master=bridge0
slave=eth0

Create a bridge:

ip link add $master type bridge

Enslave an ethernet device:

ip link set $slave master $master

Release an ethernet device:

ip link set $slave nomaster

Remove a bridge:

ip link delete $master

Using NetworkManager (permanent)

NetworkManager in Fedora 18+ already has some support for bridging. As of 2012-04-02, it is far from perfect but at least there's something to experiment with. Please file bug reports to the upstream bugzilla and link them here.

Using configuration files (keyfile)

Bridge:

[connection]
id=Bridge
uuid=fc61f6e5-8900-4c6f-915c-eb55714eb874
interface-name=bridge0
type=bridge
autoconnect=false

[bridge]
interface-name=bridge0

Slave:

[connection]
id=Slave
uuid=2e1906b1-92a4-4206-b2d3-eecfd07241e9
type=802-3-ethernet
master=fc61f6e5-8900-4c6f-915c-eb55714eb874
slave-type=bridge

[802-3-ethernet]
mac-address=52:54:00:8e:93:da

Bug reports:

bridge/bond: duplicate interface name in keyfile configuration

Using configuration files (ifcfg)

ifcfg-Bridge:

UUID=fc61f6e5-8900-4c6f-915c-eb55714eb874
TYPE=bridge
DEVICE=bridge0

ifcfg-Slave:

UUID=2e1906b1-92a4-4206-b2d3-eecfd07241e9
TYPE=Ethernet
HWADDR=52:54:00:8e:93:da
BRIDGE=fc61f6e5-8900-4c6f-915c-eb55714eb874

Note: I haven't tested this particular configuration. Feel free to test and adjust.

Using command-line interface (nmcli)

Warning: This is new development and it be available with NM 0.9.10 or an earlier snapshot.

SLAVE_MAC=00:aa:bb:cc:dd:ee

nmcli connection add name Bridge type bridge iface testbridge
nmcli connection add name Slave type ethernet mac $SLAVE_MAC
