在 OpenWRT 中将 Linux Bridge 更改为 Openvswitch

Question

我正在尝试使用 openvswitch 更改 openwrt 中的 linux 桥接器，并使用 openvswitch 包为 tp-link tlwr1043nd 编译 openwrt，它已经完成...问题是当我删除 br-lan（linux 桥接器）并替换用openvswitch，它总是错误和变砖

这是我用来更改为 ovs 的脚本： 我用((/root/ovs-tplink.sh > /dev/null 2&>1)&)& 运行它，这样它就可以在后台运行，

#!/bin/sh
OVS_BR=ovslan
#IP Controller, Port for OvS Manager, Linux Bridge
IP_CONTROLLER=192.168.0.100
PORT_CONTROLLER=6633
LINUX_BRIDGE=br-lan
echo -e "\033[0;32m Declare Necessary Variable Successful"
# Add Bridge Open vSwitch
ovs-vsctl --may-exist add-br $OVS_BR
echo -e "\033[0;32m Add OvS Bridge $OVS_BR Succesful"
sleep 2
#Delete Port if added to $LINUX_BRIDGE
for i in eth0.1 eth0.2 eth0.3 eth0.4 eth0.5 eth0.6
do
  brctl delif $LINUX_BRIDGE $i
  echo -e "\033[0;32m Delete Port $i in $LINUX_BRIDGE successful"
  sleep 1
done
# Add Port to Bridge
for i in eth0.1 eth0.2 eth0.3 eth0.4 eth0.5 eth0.6 wlan0
do
  ovs-vsctl --may-exist add-port $OVS_BR $i
  echo -e "\033[0;32m Add OvS Port $i to $OVS_BR successful"
  sleep 1
done
# Up The Interface
for i in eth0.1 eth0.2 eth0.3 eth0.4 eth0.5 eth0.6 wlan0 ovslan
do
  ifconfig $i up
  echo -e "\033[0;32m Up interface $i"
  sleep 1
done
#Set All Options Necessary for Controller
ovs-vsctl set bridge $OVS_BR stp_enable=true
echo -e "\033[0;32m Set STP Enabled True in $OVS_BR Successful"
sleep 1
ovs-vsctl set-controller $OVS_BR tcp:$IP_CONTROLLER:$PORT_CONTROLLER
echo -e "\033[0;32m Set IP:$IP_CONTROLLER as Controller in $OVS_BR and Successful"
sleep 1
ovs-vsctl set-fail-mode $OVS_BR standalone
echo -e "\033[0;32m Set Standalone Mode in $OVS_BR and Successful"
sleep 1
ovs-vsctl set bridge $OVS_BR protocols=OpenFlow13
echo -e "\033[0;32m Set OpenFlow Protocol to 1.3 in $OVS_BR Successful"
sleep 1
ovs-vsctl set-manager ptcp:6640
sleep 1
ovs-ofctl del-flows $OVS_BR
echo -e "\033[0;32m Delete Previous Flows in $OVS_BR and Successful"
sleep 1
echo -e "\033[0;32m Restart Network Service. . . . . . "
/etc/init.d/network restart
echo -e "\033[0;32m Restart Network Service Successful"
# Check Result
echo -e "\033[0;32m Result : "
ovs-vsctl show
echo " "
reboot
exit 0

这是 /etc/config/network 中的网络配置：

config interface 'loopback'
    option ifname 'lo'
    option proto 'static'
    option ipaddr '127.0.0.1'
    option netmask '255.0.0.0'

    option vid '4'
    option ports '0t 3'

    option device 'switch0'
    option vlan '5'
    option vid '5'
    option ports '0t 2'

config switch_vlan
    option device 'switch0'
    option vlan '6'
    option vid '6'
    option ports '0t 1'

我在使用openvswitch网桥时使用ovslan给出统计IP， 请大家帮我解决这个问题...

谢谢你的回答...

[已解决] 脚本很好，只需使用nano 或vi /etc/config/network 通过ssh 手动编辑局域网配置即可：

config interface 'lan'
    #option type 'bridge' <= delete this
    #option ifname 'eth0.1 eth0.2 eth0.3 eth0.4 eth0.5 eth0.6' <= edit
    option ifname 'ovslan' <= add this
    option proto 'static'
    option ipaddr '192.168.0.110'
    option netmask '255.255.255.0'
    option gateway '192.168.0.1'

然后使用 ((/root/ovs-tplink.sh > /dev/null 2&>1)&)& 运行上面的脚本，等待，然后 check with ovs-vsctl show

基本上我们：

1. 在/etc/config/network的网络配置中添加vlan

2. 禁用我们的防火墙和 DHCP 服务器，以便在我们的网络中使用父配置，因为我们使用 openvswitch（我们设置了转储 ap 路由器）

3. 像上面一样删除br-lan（删除option type 'bridge'），用你喜欢的ovs桥重命名ifname

4. 运行上面的脚本：

脚本基本上告诉：

• 添加 Openvswitch 网桥
• 删除 linux 网桥中的端口
• 在 openvswitch 中添加端口
• 在 openvswitch 中设置必要的选项

在这种情况下，我在 TP-Link TL-WR1043nd v4 中使用 OpenWRT，我认为在 v3 或 v2 中也是如此， 谢谢大家，
