1)、安装vconfig

yum install vconfig

2)、在内核加载802.1q模块

modprobe 8021q

lsmod |grep -i 8021q  (查看模块是否加载)

3)、配置vlan接口并且做桥接

vconfig add em1 13


cat  /etc/sysconfig/network-scripts/ifcfg-em1.13 

DEVICE=em1.13

ONBOOT=yes

BOOTPROTO=static

TYPE=ethernet

VLAN=yes

BRIDGE=br0


cat ifcfg-br0 

DEVICE=br0

TYPE=Bridge

BOOTPROTO=static

IPADDR=60.10.118.19

NETMASK=255.255.255.240

ONBOOT=yes



vconfig add em1 11


cat  /etc/sysconfig/network-scripts/ifcfg-em1.11

DEVICE=em1.11

ONBOOT=yes

BOOTPROTO=static

TYPE=ethernet

VLAN=yes

BRIDGE=br11



cat ifcfg-br11

DEVICE=br0

TYPE=Bridge

BOOTPROTO=static

IPADDR=60.10.118.10
