電信和網(wǎng)通的雙線路策略路由.并且在其中一條線路斷掉后自動切換為單線路，線路恢復(fù)后，恢復(fù)使用策略路由.
電信網(wǎng)關(guān) 190.168.1.10
網(wǎng)通網(wǎng)關(guān) 192.168.1.9

1 先設(shè)置用電信線路上網(wǎng).

2.添加網(wǎng)通獨(dú)立的路由表.
CODE / ip policy-routing table test1
add dst-address=0.0.0.0/0 gateway=192.168.1.9 preferred-source=0.0.0.0 comment="" disabled=no
3 在rule里添加策略路由規(guī)則
CODE / ip policy-routing rule
add src-address=0.0.0.0/0 dst-address=59.80.0.0/14 flow="" interface=all action=lookup table=test1 \
   comment="" disabled=no
..
..
此處省略
記得把main移動到最后
4、配置自動切換腳本
CODE / system script
add name="test1down" source="/ ip policy-routing table test1
\nset \[/ ip policy-routing table test1 find \
   dst-address=0.0.0.0\] gateway 190.168.1.10
\n" policy=ftp,reboot,read,write,policy,test
add name="test1up" source="/ ip policy-routing table test1
\nset \[/ ip policy-routing table test1 find \
   dst-address=0.0.0.0\] gateway 192.168.1.9
\n" policy=ftp,reboot,read,write,policy,test
add name="maindown" source="/ ip policy-routing table main
\nset \[/ ip policy-routing table main find \
   dst-address=0.0.0.0\] gateway 192.168.1.9" policy=ftp,reboot,read,write,policy,test
add name="mainup" source="/ ip policy-routing table main
\nset \[/ ip policy-routing table main find \
   dst-address=0.0.0.0\] gateway 190.168.1.10" policy=ftp,reboot,read,write,policy,test

5 配置NETWATCH用于監(jiān)視網(wǎng)絡(luò)的通斷情況
CODE / tool netwatch
add host=190.168.1.10 timeout=1s interval=20s up-script=mainup down-script=maindown comment="" disabled=no
add host=192.168.1.9 timeout=1s interval=20s up-script=test1up down-script=test1down comment="" disabled=no 文章錄入：csh    責(zé)任編輯：csh
