¿Cómo puedo poner a cero un router cisco 2600?
Buenos días el motivo de escribirte es para hacerte una
consulta o pregunta, la cual es, ¿como puedo hacer para poner
un router cisco 2600 (2610) en cero, el router en este momento
tiene una ip y una pass la cual no la se porque al equipo me lo
han dado e forma de pago, bueno si sabes algo o alguien que
sepa desconfigurarlo te lo agradeceria mucho.-
Desde ya gracias y disculpa las molestias.-

Password Recovery Procedure
for the Cisco 2600 Series Routers

Step-by-Step Procedure
Example of Password Recovery Procedure
Related Information
--------------------------------------------------------------------------------
Introduction
This document describes the procedure for recovering an enable password or enable secret passwords. These passwords are used to protect access to privileged EXEC and configuration modes. The enable password password can be recovered but the enable secret password is encrypted and can only be replaced with a new password using the procedure below.
Note: This password recovery procedure works for the following Cisco products:
Cisco 806
Cisco 827
Cisco uBR900
Cisco 1003
Cisco 1004
Cisco 1005
Cisco 1400
Cisco 1600
Cisco 1700
Cisco 2600
Cisco 3600
Cisco 4500
Cisco 4700
Cisco AS5x00
Cisco 6x00
Cisco 7000 (RSP7000)
Cisco 7100
Cisco 7200
Cisco 7500
Cisco uBR7100
Cisco uBR7200
Cisco uBR10000
Cisco 12000
Cisco LS1010
Catalyst 2948G-L3
Catalyst 4840G
Catalyst 4908G-L3
Catalyst 5500 (RSM)
Catalyst 8510-CSR
Catalyst 8510-MSR
Catalyst 8540-CSR
Catalyst 8540-MSR
Cisco MC3810
Cisco NI-2
Cisco VG200 Analog Gateway
Route Processor Module
Step-by-Step Procedure
Attach a terminal or PC with terminal emulation to the console port of the router. Use the following terminal settings:
9600 baud rate
No parity
8 data bits
1 stop bit
No flow control
The required console cable specifications are described in the Cabling Guide for RJ-45 Console and AUX Ports (Cisco's 1000 series, 2500 series, and AS5100).
If you still have access to the router, type show version and record the setting of the configuration register; it is usually 0x2102 or 0x102. Click here to see the output of a show version command.
If you don't have access to the router (because of a lost login or tacacs password), you can safely consider that your configuration register is set to 0x2102.
Using the power switch, turn off the router and then turn it back on.
Important: To simulate step 4 on a Cisco 6400, pull out and then replace the Node Route Processor (NRP) or Node Switch Processor (NSP) card.
Important: To simulate step 4 on a Cisco 6x00 using NI-2, pull out and then replace the NI-2 card.
Press Break on the terminal keyboard within 60 seconds of the power-up to put the router into ROMMON.
If the break sequence doesn't work, see Possible Key Combinations for Break Sequence During Password Recovery for other key combinations.
Type confreg 0x2142 at the rommon 1> prompt to boot from Flash without loading the configuration.
Type reset at the rommon 2> prompt.
The router reboots but ignores its saved configuration.
Type no after each setup question or press Ctrl-C to skip the initial setup procedure.
Type enable at the Router> prompt.
You'll be in enable mode and see the Router# prompt.
Important: Type configure memory or copy startup-config running-config to copy the nonvolatile RAM (NVRAM) into memory. Do not type configure terminal.
Type write terminal or show running-config.
The show running-config and write terminal commands show the configuration of the router. In this configuration you see under all the interfaces the shutdown command, which means all interfaces are currently shutdown. Also, you can see the passwords (enable password, enable secret, vty, console passwords, and so on) either in encrypted or unencrypted format. The unencrypted passwords can be re-used, the encrypted ones will have to be changed with a new one.
Type configure terminal and make the changes.
The prompt is now hostname(config)#.
Type enable secret <password> to change the enable secret password, for example.
Issue the no shutdown command on every interface that is used. If you issue a show ip interface brief command, every interface that you want to use should be "up up".
Type config-register 0x2102, or the value you recorded in step 2.
Press Ctrl-z or end to leave the configuration mode.
The prompt is now hostname#.
Type write memory or copy running-config startup-config to commit the changes.
Example of Password Recovery Procedure

Introduction
This document describes the procedure for recovering an enable password or enable secret passwords. These passwords are used to protect access to privileged EXEC and configuration modes. The enable password password can be recovered but the enable secret password is encrypted and can only be replaced with a new password using the procedure below.
Note: This password recovery procedure works for the following Cisco products:

Catalyst 8540-CSR
Catalyst 8540-MSR
Cisco MC3810
Cisco NI-2
Cisco VG200 Analog Gateway
Route Processor Module
Step-by-Step Procedure
Attach a terminal or PC with terminal emulation to the console port of the router. Use the following terminal settings:
9600 baud rate
No parity
8 data bits
1 stop bit
No flow control
The required console cable specifications are described in the Cabling Guide for RJ-45 Console and AUX Ports (Cisco's 1000 series, 2500 series, and AS5100).
If you still have access to the router, type show version and record the setting of the configuration register; it is usually 0x2102 or 0x102. Click here to see the output of a show version command.
If you don't have access to the router (because of a lost login or tacacs password), you can safely consider that your configuration register is set to 0x2102.
Using the power switch, turn off the router and then turn it back on.
Important: To simulate step 4 on a Cisco 6400, pull out and then replace the Node Route Processor (NRP) or Node Switch Processor (NSP) card.
Important: To simulate step 4 on a Cisco 6x00 using NI-2, pull out and then replace the NI-2 card.
Press Break on the terminal keyboard within 60 seconds of the power-up to put the router into ROMMON.
If the break sequence doesn't work, see Possible Key Combinations for Break Sequence During Password Recovery for other key combinations.
Type confreg 0x2142 at the rommon 1> prompt to boot from Flash without loading the configuration.
Type reset at the rommon 2> prompt.
The router reboots but ignores its saved configuration.
Type no after each setup question or press Ctrl-C to skip the initial setup procedure.
Type enable at the Router> prompt.
You'll be in enable mode and see the Router# prompt.
Important: Type configure memory or copy startup-config running-config to copy the nonvolatile RAM (NVRAM) into memory. Do not type configure terminal.
Type write terminal or show running-config.
The show running-config and write terminal commands show the configuration of the router. In this configuration you see under all the interfaces the shutdown command, which means all interfaces are currently shutdown. Also, you can see the passwords (enable password, enable secret, vty, console passwords, and so on) either in encrypted or unencrypted format. The unencrypted passwords can be re-used, the encrypted ones will have to be changed with a new one.
Type configure terminal and make the changes.
The prompt is now hostname(config)#.
Type enable secret <password> to change the enable secret password, for example.
Issue the no shutdown command on every interface that is used. If you issue a show ip interface brief command, every interface that you want to use should be "up up".
Type config-register 0x2102, or the value you recorded in step 2.
Press Ctrl-z or end to leave the configuration mode.
The prompt is now hostname#.
Type write memory or copy running-config startup-config to commit the changes.

Mientras arrranca el router, estando conectado a la consola, pulsa escape. Entras en el modo rommon.
Tienes que cambiar temporalmente el valor del registro de arranque (escribe set y fíjate en el valor 0x21xx y escríbelo. Este valor es el que luego tendrás que restaurar.
Ahora vamos a cambiarlo.
Escribe confreg 0x2142. Esto hará que se cargue el ios sin ejecutar el config, por lo que arranca limpio.
Escribe reset para salir.
El router se reinicia ignorando la configuración anterior.
Pulsa Control-C para pasar las preguntas del inicio.
Escribe enable
Si quieres borrar la configuración anterior basta con copy running-config startup-config. end.
Para ver la configuración anterior tienes que escribir copy startup-config running-config y luego show running-config.
Y modificar lo que quieras con configure terminal.
No te olvides de restaurar los valores de registro con config-register 0x2102 o el que tuvieras apuntado.
Al final sales Control Z o end y grabas con write memory
si entras en modo configuración con configure terminal.

Hola jdom2000, desde ya te agradezco por haber escrito, pero mi pregunta es como hago para entrar a la consola, que es lo que necesito o también que software necesito para entrar ahí.-
Gracias

Es muy simple, pero es necesario tener acceso físico al router.
Necesitas un ordenador con hiperterminal o cualquier programa equivalente, un cable serie estándar y el router
Conectas el cable a tu ordenador y al router en el puerto "configure" o "terminal", que suele ser de color azul.
En la configuración del programa de comunicaciones tienes que establecer la velocidad a 9600 bauds, longitud de palabra de 8 bits, sin paridad, y con un bit de stop.
Una vez que estas conectado, si te pide una contraseña y no la sabes nada que hacer, sólo puedes resetear el router y empezar con el procedimiento que te describí antes para recuperar la password.

Vas bien.
Estando conectado con el hiperterminal, si reinicias el router (lo apagas y lo enchufas), e inmediatamente pulsas esc en tu teclado, es como entrss en el modo monitor.

Tratare de darte algunos alcances para que podéis configurar tu Router Cisco series 2610.
1.- Primeramente, debes contar con un cable de consola en la cual va conectado en uno de sus extremos al puerto serial del Ordenador (PC), y el otro extremo va conectado al puerto de consola RJ-45
2.- Deberás entablar comunicación entre la PC y el Router por Hiperterminal que se encuentra en la carpeta del menu inicio accesorios\comunicacion\Hyper Terminal,... en caso de no disponer de este programa instalarlo desde el panel de control en agregar programas.
3. Una vez entablado la comunicación con el Router, aparecerá una imagen en modo Texto, en la cual deberemos ingresar en la línea de comandos "ENABLE"
paso4. Router1# CONFIGURE TERMINAL
paso5. Router1(config)# INTERFACE SERIAL 0
paso6. Router1(config)# IP ADDRESS 131.108.10.1 255.255.255.0
paso7. Router1(config)# IP HELPER-ADDRESS 131.108.20.5
paso8. Pulsar la tecla [Ctrl-Z]
paso9. Router1# WRITE MEMORY
Las direcciones IP y Mascaras que asigno tan solo son ejemplos, deberás colocar los valores reales que tenéis asignado a tu IP.
Esperando haberte ayuda en algo quedo de Ud.
Atentamente,
Lev98
P.D. Si tenéis alguna duda al respecto, escríbeme que encantado tratare de responder.

Como andas, la verdad que pobre de todas formas para hacer lo que me dijiste pero no puedo desconfigurarlo,. En este momento tengo conectado el router a mi pc por medio de hiperterminal, en lo cual me aparece así:

Esto aparece y cuando le pongo enable me pide una password, ¿cómo debo hacer para entrar en modo rommon algo así creo que es?

Deberás pulsar nuevamente <Enter> cuando aparece el mensaje de password, como también escribir
pail1 después de password:
O también intenta escribiendo el siguiente comando.
Router> enable
Router# write erase
Router# reload
Esto te permitirá borrar toda la configuración del router de la RAM y NVRAM

Conéctate a este enlace y haz un Password Recovery:
http://www.cisco.com/warp/public/474/pswdrec_2600.shtml
Después metete en modo privilegiado de esta manera
Router> enable
Router# erase nvram:
Y ya esta

En el web de CISCO (www.cisco.com) Tu problema requiere resetear el hardware. Debe haber un switch o jumper que provoca ese efecto, pero no se donde está. Busca en el web la información del modelo, seguro que esta.

¿Posees la contraseña del router?
Hola dragom gracias por escribirme, no la password del router no la tengo, lo único que se del router es la ip de la ethernet.- Si sabes algo al respecto te lo agradecería.-
Gracias nuevamente

Para accesar al router y poder cambiar el IP necesitarás el password, sin el no puedes hacer nada, una vez adentro lo demás es fácil, escribes ipconfig /help y te dirá como cambiar el IP. Suerte.
