[Dilip Srivastava]

Thia is the method for recovering the password

1.        When the following prompt appears, press the Spacebar to access
the router's bootstrap loader command prompt:

2.   Hit [Enter] to boot immediately, or space bar for command prompt.

3.   Booting [kernel] in 9 seconds...

4.        At the following prompt, enter boot -s to start up the system in
single-user mode.
ok *boot -s*

5.        At the following prompt, enter recovery to start the root password
recovery procedure.
Enter full pathname of shell or 'recovery' for root password recovery or
RETURN for /bin/sh: *recovery*

6.        Enter configuration mode in the CLI.

7.        Set the root password. For example:
user at host# *set system root-authentication plain-text-password*

For more information about configuring the root password, see Configuring
the Root Password<http://www.juniper.net/techpubs/software/junos/junos85/swconfig85-system-basics/id-10417411.html#id-10417411>

8.        At the following prompt, enter the new root password. For example:

New password: *juniper1*

Retype new password:

9.        At the second prompt, reenter the new root password.

10.     If you are finished configuring the network, commit the
configuration.
root at host# *commit*

commit complete

11.     Exit configuration mode in the CLI.

12.     Exit operational mode in the CLI.

13.     At the prompt, enter y to reboot the router.
Reboot the system? [y/n] *y*
