Tarea 1: Configurar interfaces en routers y switches
Paso 1. Asigne contraseñas y títulos en un router
Haga clic en el router R1-ISP. Inicie sesión en el router usando la ficha CLI con la contraseña cisco. Entre al modo EXEC privilegiado con la contraseña class. Entre al modo de configuración global.
Introduzca el comando interface fa0/0 para entrar al modo de configuración de interfaz para la interfaz FastEthernet. Observe el cambio en la petición de entrada. Introduzca el comando ip address 192.168.254.253 255.255.255.0 para establecer la dirección IP y la máscara de subred. Introduzca el comando description Link to Eagle Server para describir la interfaz. Introduzca el comando no shutdown para habilitar la interfaz. Introduzca el comando exit para regresar al modo de configuración global.
Introduzca el comando interface s0/0/0 para entrar al modo de configuración de interfaz para la interfaz serial. Introduzca el comando ip address 10.10.10.6 255.255.255.252 para establecer la dirección IP y la máscara de subred. En esta interfaz es donde se conecta el extremo DCE del cable serial de conexión cruzada. Introduzca el comando clock rate 64000 para establecer la interfaz para suministrar una señal de temporización. Introduzca el comando description Link to R2-Central para describir la interfaz. Introduzca el comando no shutdown para habilitar la interfaz. Introduzca el comando exit para regresar al modo de configuración global.
Presione Control+z para salir del modo de configuración. Introduzca el comando copy running-config startup-config para guardar sus cambios en la NVRAM. Presione Intro en la petición de entrada para confirmar el nombre de archivo de destino.
Verifique la configuración introduciendo los comandos show running-config y show interfaces.

Paso 2. Configure las interfaces en el otro router
Repita el Paso 1 para configurar y verificar las interfaces en el router R2-Central usando la información en la tabla anterior. Observe que la interfaz serial en R2-Central del router está conectada al extremo DTE del cable serial de conexión cruzada. Utilice descripciones como "Enlace a S1-Central" o "Enlace a R1-ISP" según corresponda.

Paso 3. Configure una interfaz en un switch
Haga clic en el switch S1-Central. Inicie sesión en el switch usando la ficha CLI con la contraseña cisco. Entre al modo EXEC privilegiado con la contraseña class. Ingrese al modo de configuración global. Ingrese el comando interface vlan 1 para ingresar al modo de configuración de interfaz para la administración de la interfaz vlan. Observe el cambio en la petición de entrada. Introduzca el comando ip address 172.16.254.1 255.255.0.0 para establecer la dirección IP y la máscara de subred. Introduzca el comando no shutdown para habilitar la interfaz. Ingrese el comando exit para regresar al modo de configuración global. Ingrese el comando ip default-gateway 172.16.255.254 para configurar la dirección a usar para llegar a los dispositivos que no están en la subred local.
Presione Ctrl+z para salir del modo configuración. Introduzca el comando copy running-config startup-config para guardar sus cambios en la NVRAM. Presione Ingresar en el símbolo de sistema para confirmar el nombre de archivo de destino.
Verifique la configuración ingresando el comando show running-config.
NOTA: Los nombres de host, contraseñas, títulos y descripciones distinguen mayúsculas y minúsculas
Al terminar esta tarea su porcentaje de finalización debe ser 100%.
