TYPE=Bridge

BOOTPROTO=dhcp

ONBOOT=yes

Warning

The line, TYPE=Bridge, is case-sensitive. It must have uppercase 'B' and

lower case 'ridge'.

Important

Prior to the release of Red Hat Enterprise Linux 5.9, a segmentation fault can

occur when the bridge name contains only uppercase characters. Please

upgrade to 5.9 or newer if uppercase names are required.

b. Start the new bridge by restarting the network service. The ifup installation

command can start the individual bridge but it is safer to test the entire network

restarts properly.

# service network restart

c. There are no interfaces added to the new bridge yet. Use the brctl show command

to view details about network bridges on the system.

# brctl show

bridge name bridge id STP enabled interfaces

installation 8000.000000000000 no

virbr0 8000.000000000000 yes

The virbr0 bridge is the default bridge used by libvirt for Network Address

Translation (NAT) on the default Ethernet device.

BRIDGE=installation

BOOTPROTO=dhcp

HWADDR=00:13:20:F7:6E:8E

ONBOOT=yes

After editing the configuration file, restart networking or reboot.

# service network restart

Verify the interface is attached with the brctl show command:
