LABORATORIOS

Laboratorio MPLS 2

Laboratorio 1: Estableciendo el CORE IGP - Ambiente de enrutamiento

OBJETIVO:

Implementar el IGP en el backbone del proveedor del servicio y establecer el enrutamiento necesario, para ello utilizar los comandos necesarios.

Tareas:

1. Interconectar las interfaces de los routers 2. Configurar las interfaces con el direccionamiento establecido en el siguiente

diagrama:

3. Configurar OSPF en los Ps y PEs en el rea 0 y verificar la correcta operacin en cada uno de los routers, todas las redes de backbone deberan aparecer en las tablas de enrutamiento de todos los routers incluidas las loopback.

Ejecutar el comando sh ip route en cada router

Laboratorio 8. Configurando QoS entre PE y CE

Objetivo:

Configurar Calidad de servicio entre el PE y CE para garantizar un adecuado funcionamiento de la VoIP.

El cliente tiene un Gateway de VoIP en cada sitio los cuales necesitan priorizarse para que la voz funcione, la IP 20.20.20.1 /32 en el CE1 y la IP 30.30.30.1/32.

Tareas: Sobre el CE:

1. Configurar un access-list 1 para clasificar a los gateway de voz.

2. Configurar un class-map con nombre VoIP para clasificar los paquetes de voz

3. Configurar un policy-map llamado QoS en donde se va a asignar 128 Kbps para la clase VoIP en donde se marcarn los paquetes con IP Precedence 5

4. Aplicar la poltica de QoS en sentido saliente sobre el interfaz que apunta al PE

Laboratorio MPLS 42

En el PE:

1. Configurar un class-map llamado VoIP que clasifique los paquetes marcados con IP Precedence 5

2. Configurar un policy-map llamado QoS que asigne 128 Kbps de BW a las clase VoIP

3. Aplicar la poltica QoS sobre la interfaz que apunta al CE

Verificar que las polticas estan aplicadas en las interfaces del router CE y PE con el comando sh policy-map interface

PE1# sh policy-map interface f1/0 FastEthernet1/0

Service-policy output: QoS

Class-map: VoIP (match-all) 0 packets, 0 B/bytesytes 30 second offered rate 0 bps, drop rate 0 bps Match: ip precedente 5 Queueing Strict Priority Output Queue: Conversation 264 Bandwidth 128 (kbps) Burst 3200 (Bytes) (pkts matched/bytes matched) 0/0 (total props./bytes props) 0/0
