Verificación

En esta sección encontrará información que puede utilizar para confirmar que su configuración esté funcionando correctamente.

La herramienta Output Interpreter (sólo para clientes registrados) permite utilizar algunos comandos “show” y ver un análisis del resultado de estos comandos.

  • muestre el detalle crypto isakmp sa — Visualiza todas las asociaciones de seguridad actuales del Internet Key Exchange (IKE) (SA) en un par.

  • show crypto ipsec sa — Muestra la configuración actual utilizada por las SA actuales

  • active del show crypto engine connections — Visualiza un resumen de la información de la configuración para los motores de criptografía.

  • show ip route – Muestra el estado actual de la tabla de ruteo.

Troubleshooting

En esta sección encontrará información que puede utilizar para solucionar problemas de configuración. Para más información sobre el troubleshooting, vea por favor el Troubleshooting de IP Security - Entendiendo y con los comandos debug.

Procedimiento de Troubleshooting

Sigue estas instrucciones de resolver problemas su configuración.

  1. Genere las claves RSA en el router 101.

    101#
    101#
    101#conf t
    101(config)#ip domain-name cisco.com
    101(config)#crypto key generate rsa ?
      general-keys  Generate a general purpose RSA key pair for signing and
                    encryption
      usage-keys    Generate seperate RSA key pairs for signing and encryption
    
    
    101(config)#crypto key generate rsa
    The name for the keys will be: 101.cisco.com
