Introducción. Protocolo PPP o también llamado (point to point protocol) este es un protocolo que

da comunicación a nivel de enlace entre dos.

Particularmente se utiliza para establecer conexiones hacia internet de una

computadora a través de un modem con su proveedor de servicios. Pocas veces

es usado en una red banda ancha.

Principalmente facilita dos funciones en una red y estos son. Autentificación que

se permite el acceso por medio de una clave. Y asignación de IP dinámica.

PPP consta de fases:

Una de ellas es establecimiento de la conexión.

Autentificación.

Configuración de la red.

Transmisión.

Terminación.

Y este cuenta con todas las propiedades de un protocolo de nivel de enlace.

Objetivos. Comprender y saber la utilización del protocolo PPP

Configurar de manera básica PPP

Autentificar el protocolo por medio PAP o CHAP

Desarrollo. Se tiene una red de computadoras de 9 ROUTERS 2 SWITCHES a la cual se le debe implementar el

protocolo PPP para que todo el estudiantado pudiese implementar sus conocimientos se modificó

la red puesta en el laboratorio.

Por consiguiente los ROUTERS 1, 2, 3, 4 serían copias de 11, 22, 33, 44 lo que cambiarían en su

configuración seria su IP ROUTER 5 es el que conecta estas dos redes.

Explicación:

ROUTER 1, 11, 2, 22, 3, 33, 4, 44 y 5.

Para el ROUTER 11 el modelo cisco 2901.









R 11 tiene una red aparte con un switch por gigaethernet 0/0

Se hizo una conexión de fastethernet entre el R33 y el switch44 de misma forma se hizo una

conexión entre R22 y switch44 por fastethernet.

Adicionalmente siguiendo la topología estipulada por el profesor se conectó por medio serial el

puerto 0 (DTE) del R22 al puerto 0/0/0 (DCE) de R11.

Para R33 se conectó en el puerto 0/0/0 (DTE) en este caso al puerto 0/0/1 del R11 (DCE).

Para la comunicación entre R44 y el grupo de R33 y R22 intermedio hay un Switch el cual se le

hace la configuración básica.

Siguiendo la topología estipulada por el profesor se conectó por medio serial el puerto 0/0/0 (DCE)

del R44 al puerto 0/0/0 (DTE) de R5.

Y R5 se conecta a su contraparte de la red.

Siguiendo el orden de la topología y numeración el ROUTER’s en estos se configuran los siguientes:

El banner de bienvenida.

Se utilizó el comando “no ip domain-lookup” para evitar la espera y reacción de ROUTER o

SWTCH.

Se le asignó como nombre a este ROUTER: R22 (Comando hostname). ROUTER: R33

(Comando HOSTNAME).

Se configuraron contraseñas para el modo privilegiado, el modo consola y el modo VTY

por si se necesitaba control desde una computadora de la red.

Se ejecutó el comando “logging synchronous” para evitar que las notificaciones del

sistema.

Para R22 la red 192.168.22.0/30 en el puerto Se 0 e asignar con IP 192.168.22.2.

Para R33 la red 192.168.33.0/30 en el puerto Se 0/0/0 e asignar con IP 192.168.33.2.

Para R22 la red 192.168.40.0/30 para el puerto Fa 0/0 e asignar con IP 192.168.40.2.

Para R33 la red 192.168.40.0/30 para el puerto Fa 0/0 e asignar con IP 192.168.40.3.

En las interfaces que utilizaremos se coloca el comando “no shutdown” para levantarlas.

Para R22 serial 0 se utiliza el enlace PPP con autentificación CHAP.

Para R33 serial 0/0/0 se utiliza el enlace PPP con autentificación PAP.

Se aplica el DEBUG PPP AUTHETICATION para saber si en realidad se está ejecutando

entre los enlaces.

Configuración de OSPF y la autentificación.

Por ultimo verificar que todo se encuentra bien y hay comunicación entre ellos.
