我用的是一台现网中的核心高端路由器MX 960做的。。。
1.重启MX960，通过console线(RJ-45转DB9接口)连到路由器
2.当出现下面的提示时，快速按下空格键(有时候设置的等待时间不一样)
Hit [Enter] to boot immediately, or space bar for command prompt.
Booting [/kernel] in 5 second...
3.让其自动加载，当出现下面提示时，输入：(空格)boot -s
Type '?' for a list of commands, 'help' for more detailed help.
OK
4.回车;然后输入：recovery 回车，让其自动启动。
启动过程中会提示缺少或无法在指定默认目录下找到系统密码所在db文件，所以要手动创建;上面有创建方法和相应的操作步骤
5.进入恢复模式：
# /user/libexec/ui/recovery-mode
6.创建新的管理密码：
。。。(上面有操作方法和步骤。。不详述)
7.保存配置，退出。
8.重启系统，即可完成密码破解。
