Examen practico del ccie

[pic]

Hoy cuelgo mi primer laboratorio para preparar el examen práctico del CCIE, el laboratorio es un laboratorio básico de OSPF, RIP y túneles GRE, y todo el laboratio está hecho con routers Cisco 2691.

Se trata de una red OSPF en area 0, excepto el enlace entre R0 y R4 que está en area 1 siendo este último área un área stub. El objetivo es extender rutas mediante RIP entre R2 y R4mediante RIP utilizando un túnel GRE, de forma que esas rutas no se vean por los routers intermedios.

El área 0 se trata de un área con topología de broadcast, así que el switch es símplemente un switch transparente. El laboratorio completo está realizado con GNS3.

A continuación configuraciones y pruebas:
