第一 ip设好

/ ip address
add address=192.168.1.1/24 network=192.168.1.0 broadcast=192.168.1.255   interface=lan comment="" disabled=no
add address=电信地址/掩码 network=自动设置 broadcast=自动设置
  interface=TEL comment="" disabled=no
add address=网通地址/掩码 network=自动设置 broadcast=自动设置
  interface=CNC comment="" disabled=no

这里如果你有 PPPOE的 ADSL 也可以+上 ADSL

记住要改MSS

/ ip firewall mangle
add chain=forward out-interface=pppoe-out1 protocol=tcp tcp-flags=syn   action=change-mss new-mss=1400 comment="" disabled=no

/ ip firewall nat
add chain=srcnat src-address=192.168.1.0/24 action=masquerade comment=""   disabled=no

--------------------------------------------------------------------------------------------------

第2步 添加 网通的路由网关

电信的服务器在网络中占了绝大多数

所以不需要考虑电信的服务器

add dst-address=0.0.0.0/0 gateway=电信网关 check-gateway=ping distance=0   scope=255 target-scope=10 comment="TEL" disabled=no

（最后这条的意义就是保证在上面找不到网通的网关后 IP包自动走电信的线路 如果想拷贝这个规则 就用替换功能 换上具体的IP就可以了）

-------------------------------------------------------------------------------------------------------

第3步 设置好监控的开关

/ tool netwatch
add host=电信网关 timeout=1s interval=1m up-script=dxup   down-script=dxdown comment="TEL" disabled=no
add host=网通网关 timeout=1s interval=1m up-script=CNCup   down-script=CNCdown comment="CNC" disabled=no

--------------------------------------------------------------------------------------------------------

第四写好脚本自动切换

/ system script
add name="dxup" source="/ip route set \[/ip route find comment=TEL\] gateway   电信网关\n" policy=ftp,reboot,read,write,policy,test,winbox,password

add name="CNCup" source="/ip route set \[/ip route find comment=CNC\] gateway   网通网关\n" policy=ftp,reboot,read,write,policy,test,winbox,password

add name="dxdown" source=":if \(\[/tool netwatch get \[/tool netwatch find   comment=CNC\] status\]=\"down\"\) do {/ip route set \[/ip route find   comment=TEL\] gateway \[/ip address get \[/ip address find   interface=pppoe-out1\] network\]} else {/ip route set \[/ip route find   comment=TEL\] gateway 网通网关}"   policy=ftp,reboot,read,write,policy,test,winbox,password

add name="CNCdown" source=":if \(\[/tool netwatch get \[/tool netwatch find   comment=TEL\] status\]=\"down\"\) do {/ip route set \[/ip route find   comment=CNC\] gateway \[/ip address get \[/ip address find   interface=pppoe-out1\] network\]} else {/ip route set \[/ip route find   comment=CNC\] gateway 电信网关}"   policy=ftp,reboot,read,write,policy,test,winbox,password 在电信的 光纤断的 时候 判断1下 网通的光纤是否是断了 (如果也断了就换ADSL)

如果没有断就上 网通的光纤 (反过来 网通的断了也一样)

针对很多地方光纤晚上都会断线的情况

如果不用ADSL 就更简单了，自己看吧
