Actualizar IOS de router cisco

  1. 1. ACTUALIZACIÓN DE IOS ROUTER CISCO Cisco CCNA Security, Guía para actualización de IOS Desarrollada por Pedro Antonio Villalta, Ingeniero en Sistemas y Redes. Enero de 2014. Pasos para realizar la copia de una nueva IOS en un router CISCO, éste proceso es muy importante si necesitamos una IOS específica para la realización de guías prácticas, en este caso las guías del módulo CCNA Security. La imagen IOS que he utilizado en ésta guía es la que podrán encontrar como C1841 en GNS3, en el caso no la tengas puedes descargarla desde mi GoogleDrive. Software utilizado en ésta guía:   Putty TFTP Server Y se necesita también un archivo de IOS que se quera copar en router. La utilizada en el ejemplo puedes descargarla en siguiente enlace. https://googledrive.com/host/0BxfUn2LNLVPeVUJMRTJ0N0xQbXM/c1841-advsecurityk9-mz.124-24.T7.bin CONFIGURACION DE ROUTER PARA MODO LECTURA-ESCRITURA Iniciamos la copia verificando que el router este en modo escritura, de lo contrario los cambios no tendrán efecto. Entramos a consola del router y usamos el comando Show versión Este comando dará como resultado elementos varios sobre el dispositivo y al final indicará la configuración del registro. En el caso indique número de registro 0x2142 por ejemplo debemos cambiar el registro a 0x2102. ACTUALIZACIÓN DE IOS ROUTER CISCO PEDRO ANTONIO VILLALTA (PAVILLALTA@GMAIL.COM)
  2. 2. ACTUALIZACIÓN DE IOS ROUTER CISCO Usamos el comando Config-register 0x2102 para cambiar de registro a modo lectura y escritura ACTUALIZACIÓN DE IOS ROUTER CISCO PEDRO ANTONIO VILLALTA (PAVILLALTA@GMAIL.COM)
  3. 3. ACTUALIZACIÓN DE IOS ROUTER CISCO INSTALACIÓN DE SOFTWARE TFTP Directorio de instalación de TFTP. Copiar la imagen IOS con extensión bin en el directorio de instalación. En el menú View seleccionar Options para especificar la ruta de trabajo de TFTP Server. ACTUALIZACIÓN DE IOS ROUTER CISCO PEDRO ANTONIO VILLALTA (PAVILLALTA@GMAIL.COM)
  4. 4. ACTUALIZACIÓN DE IOS ROUTER CISCO CONFIGURACION DE DIRECCIONES IP EN ROUTER Y SERVIDOR El siguiente paso es conectar el cable de consola desde el router al puerto COM1 de la computadora que usaremos como servidor para copiar la IOS al dispositivo. Configuramos la red asignando direcciones IP, por ejemplo: Configurar IP para la PC en propiedades de red. 192.168.1.2 255.255.255.0 192.168.1.254 Para el router podemos usar la dirección IP siguiente: 192.168.1.1 COMANDOS PARA COPIA DE LA NUEVA IOS Aplicar comando reload Inmediatamente en el proceso de reload iniciar modo rommon con la combinación de Teclas Control+pausa, entraremos a modo rommon como en la siguiente imagen. ACTUALIZACIÓN DE IOS ROUTER CISCO PEDRO ANTONIO VILLALTA (PAVILLALTA@GMAIL.COM)
  5. 5. ACTUALIZACIÓN DE IOS ROUTER CISCO Aplicar comando set Para visualizar las variables de entorno cargadas por defecto. ACTUALIZACIÓN DE IOS ROUTER CISCO PEDRO ANTONIO VILLALTA (PAVILLALTA@GMAIL.COM)
  6. 6. ACTUALIZACIÓN DE IOS ROUTER CISCO Ingresar script de comandos siguiente en modo rommon: IP_ADDRESS = 192.168.1.1 (La ip del router) IP_SUBNET_MASK = 255.255.255.0 (Mascara de red) DEFAULT_WATEWAY=192.168.1.253 (Puerta de enlace) TFTP_SERVER=192.168.1.2 (La ip de la pc servidor) TFTP_FILE=c1841-advsecurityk9-mz.124-24.T7.bin (Nombre de imagen IOS) Es preferible ingresar cada comando manualmente sin usar la opción de copiado, y asegurarse de teclear de forma correcta para evitar errores al momento de usar el comando Tftpdnld. Si se presenta mensajes de error se debe tratar de corregir el error asignando otras direcciones IP hasta que sean aceptadas. Esta son otras direcciones que podemos usar: IP_ADDRESS = 172.16.0.1 (La ip del router) IP_SUBNET_MASK = 255.255.255.0 (Mascara de red) DEFAULT_WATEWAY=172.16.0.253 (Puerta de enlace) TFTP_SERVER=172.16.0.2 (La ip de la pc servidor) TFTP_FILE=c1841-advsecurityk9-mz.124-24.T7.bin (Nombre de IOS) También se debe revisar que en el programa TFTP esté bien direccionado el directorio y que el nombre del archivo este correcto. ACTUALIZACIÓN DE IOS ROUTER CISCO PEDRO ANTONIO VILLALTA (PAVILLALTA@GMAIL.COM)
  7. 7. ACTUALIZACIÓN DE IOS ROUTER CISCO Probar nuevamente el comando set para verificar las nuevas variables de entorno. El siguiente paso es reiniciar el router para que inicie con la nueva configuración: Commando reset para reiniciar y salir de modo rommon. En la ventana que solicita mostrar diálogos de inicio podemos dar no a la pregunta para evitar la carga de los diálogos de inicio y acelerar el arranque. ACTUALIZACIÓN DE IOS ROUTER CISCO PEDRO ANTONIO VILLALTA (PAVILLALTA@GMAIL.COM)
  8. 8. ACTUALIZACIÓN DE IOS ROUTER CISCO Aplicar el comando Tftpdnld Algunas veces este comando genera advertencias solicitando aplicar nuevamente el comando reset. Se recibe mensaje que la Flash actual se perderá, confirmar la copia de la nueva IOS en el dispositivo. Tecleamos “y” ACTUALIZACIÓN DE IOS ROUTER CISCO PEDRO ANTONIO VILLALTA (PAVILLALTA@GMAIL.COM)
  9. 9. ACTUALIZACIÓN DE IOS ROUTER CISCO Al aceptar la copia de la nueva IOS iniciará el proceso, en la consola de Putty deberíamos visualizar lo siguiente. ACTUALIZACIÓN DE IOS ROUTER CISCO PEDRO ANTONIO VILLALTA (PAVILLALTA@GMAIL.COM)
  10. 10. ACTUALIZACIÓN DE IOS ROUTER CISCO Y en el TFTP lo siguiente. En consola y en TFTP esperamos que finalice la copia, se debe ver el mensaje de copia exitosa de lo contrario se debe repetir el proceso. Cuando finaliza la copia aplicamos nuevamente el comando reset para cargar la nueva IOS configurada en el router. Reset para cargar la configuración del router con la nueva flash.
