Linux下bond和br建立vlan的方法

我们的宿主机上做了4网卡bonding，然后需要上升到br，两个网卡都需要做上vlan。
比如172.18.30.1，想在上面增加一个VLAN段202，然后在上面生产一台虚机172.18.19.2
就需要增加一个bond0.202以及br0.202
做法如下:
cd /etc/sysconfig/network-scripts
cp ifcfg-bond0.199 ifcfg-bond0.202
vi ifcfg-bond0.202
DEVICE=bond0.202
ONBOOT=yes
USERCTL=no
BRIDGE=br0.202
VLAN=yes
cp ifcfg-br0.199 ifcfg-br0.199
vi ifcfg-br0.202
DEVICE=br0.202
BOOTPROTO=static
ONBOOT=yes
TYPE=Bridge
然后启动这两个网卡，启动顺序很重要！！！
ifup bond0.202
ifup br0.202
注意，执行完以后务必检查一下两个网卡是否UP
然后产虚机就好
./vm.sh create -b br0.202 -c 4 -m 4096 -d 40 -i 172.18.19.2 -k 255.255.255.0 -g 172.18.19.254 -q 172.18.30.1 -r 172.18.30.2 ucarp-18-19-2
