EIGRP (Enhanced Interior Gateway Routing Protocol)

EIGRP (Enhanced Interior Gateway Routing Protocol)

EIGRP (Protocolo de Enrutamiento de Gateway Interior Mejorado), protocolo mixto basado en IGRP, basado en una métrica de vector distancia, pero que manda actualizaciones de las entradas de las tablas que han cambiado por haber sido alterado el estado de alguna máquina de su red.

Contrariamente a RIP y a OSPF, que son estándares, este es un protocolo creado por CISCO que toma las ventajas de los dos primeros. En principio, la métrica de este protocolo es compuesta, ya que tiene en cuenta no sólo el ancho de banda, sino también la congestión, el delay y la confiabilidad de cada enlace.

Como mejora fundamental agrega, en el momento de calcular cada ruta, la posibilidad de calcular también una Ruta de Backup, de manera de poder utilizarla inmediatamente al enterarse de un cambio de topología o una caída. Esto le brinda una convergencia mucho más rápida que el OSPF.

Su desventaja es que, en principio, es un protocolo propietario, aunque esto podría llegar a ser un punto de discusión muy filosófico, porque en todo caso, cada vez es más difícil encontrar la frontera entre lo propietario y lo estándar (a nadie se le ocurriría decir que lo que proponga CISCO en materia de Redes sea algo a considerar como “no estándar”). De cualquier manera, al presente, el EIGRP ya posee varios RFCs (Request For Comments), que son los documentos iniciales mediante los cuales se estandarizan las reglas de la Internet.

Ventajas del EIGRP

Convergencia rápida. EIGRP usa Diffusing Update Algorithm (DUAL) para alcanzar rápida convergencia. Un router usando EIGRP almacena todas las posibles rutas de respaldo para el destino, de tal forma que puede adaptarse rápidamente a rutas alternativas. Si no hay una ruta apropiada o una ruta de respaldo en la tabla de routing local, EIGRP solicita a sus vecinos descubrir una ruta alternativa. EIGRP transmite esta solicitud hasta que encuentra una alternativa ruta.

Uso reducido del Ancho de Banda. EIGRP no realiza actualizaciones periódicas. En ves de eso, este envía una actualización parcial cual el camino o la métrica a cambiado para la ruta. Cuando la información de camino a cambiado, DUAL envía una actualización solo del enlace mas que la tabla entera. DUAL envía la info solo a los routers que lo requieren, en contraste al protocolo Link-State, el cual un update es transmitido a todos los routers Link-State dentro de un área.

Conectividad a través de todos los protocolos de capa de enlaces de datos y topologías. EIGRP no requiere configuración especial para trabajar con protocolos de capa 2. OSPF usa diferentes configuraciones para diferentes protocolos de capa 2, tal como Ethernet y Frame Relay. Comandos que son únicos en EIGRP te ayudan a limitar la cantidad de ancho de banda que EIGRP usas sobre enlaces WAN.

Configuración del protocolo EIGRP

Como se trata de un protocolo propietario que sólo es implementado en los routeres de Cisco es posible detallar aquí la forma de realizar una configuración básica de EIGRP.

1. Use lo siguiente para habilitar EIGRP y definir el sistema autónomo:

router(config)#router eigrp autonomous-system-number

El número de sistema autónomo se usa para identificar todos los routers que pertenecen a la internetwork. Este valor debe coincidir para todos los routers dentro de la internetwork.

2. Indique cuáles son las redes que pertenecen al sistema autónomo EIGRP en el router local mediante la siguiente orden:

router(config-router)#network network-number

Network-number es el número de red que determina cuáles son las interfaces del router que participan en EIGRP y cuáles son las redes publicadas por el router. La orden network configura sólo las redes conectadas. Por ejemplo, la red 3.1.0.0, que se encuentra en el extremo izquierdo de la Figura principal, no se encuentra directamente conectada al router A. Como consecuencia, esa red no forma parte de la configuración del Router A.

3. Al configurar los enlaces seriales mediante EIGRP, es importante configurar el valor del ancho de banda en la interfaz. Si el ancho de banda de estas interfaces no se modifica, EIGRP supone el ancho de banda por defecto en el enlace en lugar del verdadero ancho de banda. Si el enlace es más lento, es posible que el router no pueda converger, que se pierdan las actualizaciones de encaminamiento o se produzca una selección de rutas por debajo de la óptima. Para establecer el ancho de banda para la interfaz, aplique la siguiente sintaxis:

router(config-if)#bandwidth kilobits

Sólo el proceso de encaminamiento utiliza la orden bandwidth y es necesario configurar la orden para que coincida con la velocidad de línea de la interfaz. 4. Cisco también recomienda agregar la siguiente orden a todas las configuraciones EIGRP:

router(config-router)#eigrp log-neighbor-changes

Esta orden habilita el registro de los cambios de adyacencia de vecinos para monitorear la estabilidad del sistema de encaminamiento y para ayudar a detectar problemas.

IGRP (Protocolo de Enrutamiento de Gateway Interior)

2010-11-25T23:22:00.004-06:00

IGRP (Protocolo de Enrutamiento de Gateway Interior)

IGRP (Protocolo de Enrutamiento de Gateway Interior), desarrollado por Cisco System, es un protocolo de enrutamiento por vector de distancia que usa una métrica compuesta basada en diferentes variables de red, como ancho de banda, unidades máximas de transmisión (MTU), confiabilidad, etc. Envía actualizaciones de las tablas de enrutamiento cada 90 segundos.

Fue diseñado para corregir algunos de los defectos de RIP y para proporcionar un mejor soporte para redes grande con enlaces de diferentes anchos de banda.

IGRP es un protocolo de enrutamiento basado en vectores de distancia desarrollado por CISCO, sus ventajas son:

Escalabilidad mejorada: Enrutamiento en redes m疽 grandes, posee un n伹ero m痊imo predeterminado de 100 saltos, aunque puede ser configurado con hasta 255 saltos.

Métrica sofisticada: M騁rica compuesta que proporciona una mayor flexibilidad en la selección de rutas. Se usa el retraso de interconexión y el ancho de banda y se pueden incluir otros parámetros como la fiabilidad, la carga y la MTU.

Soporte de m伃tiples rutas: IGRP puede mantener hasta un máximo de seis rutas de coste diferente entre redes de origen y destino. Se pueden usar varias rutas para aumentar el ancho de banda disponible o para conseguir redundancia de rutas. IGRP permite actualizaciones desencadenadas.

Mejorar ancho de banda del XP Professional

2010-10-22T04:28:00.001-05:00

Mejorar ancho de banda del XP Professional

Windows XP se reserva el 20% del ancho de banda disponible, con el fin de ejecutar aplicaciones especiales. La “retención” se produce mediante el denominado el programador de paquetes QoS (Quality of Service – Calidad del Servicio), encargado de la optimización de redes locales.
Sin embargo, para los usuarios privados, que sólo tienen un PC en casa, QoS no es una función necesaria; sino todo lo contrario. Windows XP reserva el 20% del ancho de banda aunque el usuario cancele la función QoS. También se puede optar por desintalar el Programador de paquetes QoS si no tenemos ninguna Red Local.
1) Entrar como administrador.
2) Inicio, ejecutar, escribid: gpedit.msc
3) Aparecen las directivas de grupo, id a Configuración de Equipo.
4) Plantillas Administrativas
5) Red (Network)
6) Programador de Paquetes Qos
7) Doble click en Limitar el ancho de banda reservado
8) Habilitarlo y poner el 0% en Límite de Ancho de Banda.
9) Aplicar y Aceptar
10) Id a propiedades red y comprobad que está marcado el Programador de Paquetes Qos.

Mejorar las transferencias en red de archivos

2010-10-22T04:26:00.003-05:00

Mejorar las transferencias en red de archivos

Windows normalmente limitará la cantidad de memoria RAM que el sistema podrá utilizar para las operaciones de entrada y salida de datos en conexiones de red, algo que podemos modificar mediante la edición del registro
La utilidad de este ajuste cuestionable para usuarios que no tengan instalado en el sistema algún tipo de servidor, ya que básicamente este ajuste mejora el rendimiento de entrada/ salida del ordenador cuando se están realizando una cantidad grande de transferencias de archivos y operaciones similares. Este ajuste no hará mucho en sistemas que no tengan grandes cantidades de memoria, pero sistemas con más de 256 Mb de RAM generalmente encontrarán una mejora en el rendimiento estableciendo este valor entre 16 y 32 Mb. El valor por defecto es 0.5Mb (512Kb). Para modificar el ajuste automático de esta configuración, iniciaremos la herramienta de edición del registro de sistema, con el comando “regedit.exe” en el menú Inicio/Ejecutar. Localizaremos la clave HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management y crearemos o modificaremos el valor DWORD de nombre “IoPageLockLimit” (sin las comillas) con un número, cuyo valor será equivalente al máximo de bytes que se utilizarán para las operaciones de entrada y salida, de forma que tendremos que multiplicar el número de megabytes x 1024 x 1024
NOTA: Modificar este ajuste puede causar problemas de estabilidad con dispositivos de sistema, como problemas relacionados con OpenGL o SCSI, en cuyo caso volveremos al ajuste predeterminado.

Acelerar apagado del XP

2010-10-22T04:21:00.001-05:00

Acelerar apagado del XP

Editor de registro. Para ello pinchamos en INICIO -> Ejecutar: "regedit" (sin comillas) y le damos a enter. Entramos luego hasta el nivel HKEY_CURRENT_USER -> Control Panel -> Desktop y localizamos allí la clave "WaitToKillAppTimeout" y hacemos doble clic sobre ella. A continuación cambiamos el valor de 20.000 (que ya trae por defecto) por el de 4.000. Ahora, y sin salir del editor, accedemos a HKEY_LOCAL_MACHINE -> System -> Current Control -> Control, para localizar de nuevo la clave "WaitToKillAppTimeout" y repitiendo la misma operación de antes cambiamos el valor de 20.000 a 4.000.

TIPO DE FORMATEO DE DISCOS DUROS

2010-10-19T01:52:00.004-05:00

Hay dos formas para formatear el disco duro. Una es haciendo un formateo a bajo nivel y la otra a alto nivel.

Bajo Nivel: Consiste en colocar marcas en la superficie magnética para dividirlo en sectores físicos, los cuales pueden ser luego referenciados indicando la cabeza lectora, el sector y cilindro que se desea leer. Reescribe la geometría del disco duro, el MBR y define el tamaño de los sectores de acuerdo a la densidad del disco duro. Este proceso puede tardar muchas horas dependiendo de la densidad del disco. Aunque cuando sale de fábrica viene ya formateado a bajo nivel, hay que darle de nuevo un formateo al tener que crear un sistema de archivos.

Este sistema de formateo es un poco peligroso ya que podemos “estropear” el disco duro si mediante el proceso se detiene o si no se utiliza una herramienta adecuada. Para ello, muchos fabricantes dejan a nuestra disponibilidad en su web, su herramienta para este tipo de proceso. Además, es muy importante saber que al realizar un formateo a bajo nivel, toda la información que había en el disco duro ha sido borrada totalmente, sin recuperación alguna.

También, con este formateo puedes llegar a “reparar” el disco duro si tenía sectores defectuosos.

Alto Nivel: Con este sistema no se llegan a perder los datos que hay almacenados en el disco duro, lo que realmente hace es borrar las tablas de partición que albergan la información de cómo y dónde se encuentran los datos en el disco duro. Concretamente es el índice maestro de arranque (MBR) que es un sector del disco que inicia en 001.

Hay dos formas de hacerlo, de forma rápida o completa. Tanto uno como el otro hacen lo descrito anteriormente, borra la tabla de partición, pero la diferencia es que el completo, además de borrar la tabla, examina todos los sectores del disco duro en busca de errores.

PRACTICA 4 PROTOCOLO RIP

PRACTICA 4 INTERCONEXION DE REDES BOSON NETSIM v5.27

Esta practica se trata de una simulación de una red con las herramientas Boson NetSim v5.27. En este software simularemos una red que consta de 4 routers (modelo 2505) A cada uno de los routers secundarios se le ha conectado un SWITCH (modelo 1912) de los que colgarán los terminales. y 4 computadoras.

Los routers están conectados entre si por los interfaces. estos son Serial 0 y Serial 1 para conectar routers entre sí (s1 con s1 no es posible conectarse, ya que uno debe ser el DCE y el otro es el DTE), y los Ethernet 0 que son los que se encargarán de conectarse a los switches.
