ip route flush table tel
ip route add default via 192.168.6.1 dev eth0 src 192.168.6.2 table tel
ip rule add from 192.168.6.2 table tel
ip route flush table cnc
ip route add default via 192.168.7.1 dev eth1 src 192.168.7.2 table cnc
ip rule add from 192.168.7.2 table cnc
OK~可用将以上命令添加到/etc/rc.local里，这样重启后就不用重新添加了...
