RHEL6配置網橋

1、由於NetworkManager不支持bridging，所以，需要disable NetworkManager servcie.

# /etc/init.d/NetworkManager stop
# service NetworkManager off

2、# cd /etc/sysconfig/network-scripts/

# vi ifcfg-eth0 如下

DEVICE=eth0
TYPE=Ethernet
HWADDR=1c:6f:65:dd:d4:d8
NM_CONTROLLED=yes
ONBOOT=yes
BOOTPROTO=dhcp
BRIDGE="vSwitch0"

# vi ifcfg-vSwitch0 橋配置文件

DEVICE=vSwitch0
HWADDR=1c:6f:65:dd:d4:d8
TYPE=Bridge
BOOTPROTO=static
IPADDR=10.10.10.65
NETMASK=255.255.255.0
GATEWAY=10.10.10.1
BROADCAST=10.10.255.255
DNS1=10.10.10.21
ONBOOT=yes

3、重啟系統

# init 6

搞定

4、查看橋

# brctl show
bridge name bridge id STP enabled interfaces
vSwitch0 8000.1c6f65ddd4d8 no eth0
vnet0
virbr0 8000.000000000000 yes

如果要打開vSwitch0的STP，操作如下：

# brctl stp vSwitch0 on
# brctl show
bridge name bridge id STP enabled interfaces
vSwitch0 8000.1c6f65ddd4d8 yes eth0
vnet0
virbr0 8000.000000000000 yes
