Desafío OSPF
Lab. 3.5
Desafío 3.5 Lab. OSPF
1. Configurar las interfaces según el direccionamiento IP del diagrama.
2. Configurar el BW para reflejar el actual BW de todos los enlaces seriales.
3. Configurar OSPF con las interfaces y áreas según el diagrama.
4. Configurar R2 para la sumarización del área 20 con mascara lo mas especifica posible.
5. Realizar el link entre R1 y R2 con la red OSPF tipo broadcast, con R1 como el DR.
6. Configurar R1 para que siempre origine una ruta por defecto.
7. Modificar el enlace entre R2 y R3 para que los tiempos de "hello" y "dead" sean el doble de los
valores por defecto.
8. Hacer que el enlace entre R2 y R3 tenga un costo de 500.
9. Configurar el área 34 para que sea totalmente un área "Stubby"
10. Utilizar autenticación MD5 con la palabra clave "cisco" sobre el enlace entre R3 y R4.
11. Descubrir la publicación oculta en la topología que usted necesita direccionar para tener
conectividad total.
12. Hacer correr un script Tcl en todos los routers para verificar que hay conectividad entre el
direccionamiento IP en la topología.
