在线求解：双线策略自动切换问题，请朋友们帮忙

benben418

用的是ros2.96版，网通网关192.168.1.1，电信网关192.168.0.1，设置192.168.1.1为默认路由，
add dst-address=0.0.0.0/0 gateway=192.168.1.1 check-gateway=ping \
    distance=0 scope=255 target-scope=10 comment="" disabled=no
并添加其他电信IP段走192.168.0.1网关。
经测试，双线策略正常，问题出在断线自动切换上，自动检测网络状态正常，但是电信断线可以自动走网通网关，而网通断线却走不了电信网关，这时候只有电信段能上，网通就掉了。请大家帮忙指点一下，我的切换脚本：
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 \
  192.168.0.1\n" policy=ftp,reboot,read,write,policy,test,winbox,password

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

add name="dxdown" source=":if \(\[/tool netwatch get \[/tool netwatch find \
  comment=CNC\] status\]=\"up\"\) do {/ip route set \[/ip route find \
  comment=TEL\] gateway 192.168.1.1}" \
  policy=ftp,reboot,read,write,policy,test,winbox,password

add name="CNCdown" source=":if \(\[/tool netwatch get \[/tool netwatch find \
  comment=TEL\] status\]=\"up\"\) do {/ip route set \[/ip route find \
  comment=CNC\] gateway 192.168.0.1}" \
  policy=ftp,reboot,read,write,policy,test,winbox,password
