Enhaced Interior Gateway Routing Protocol – EIGRP<\/span><\/span><\/span><\/strong><\/h4>\n\n\n\n

Su distancia Administrativa interna es de 90 y la externa de 170, para que un router configurado con eigrp pueda intercambiar informaci\u00f3n entre sus routers vecinos es necesario que todos esos routers est\u00e9n configurados con el mismo id de proceso. Por la tanto, con este id de proceso se toma a un conjunto de routers como un sistema aut\u00f3nomo (AS) supuestamente, aunque no es la forma correcta de nombrarlo y s\u00f3lo ellos pueden intercambiar informaci\u00f3n de enrutamiento entre s\u00ed.

Su configuraci\u00f3n es de la siguiente manera:<\/p>\n\n\n\n

Router(config)# router eigrp process-id\nRouter(config-router)# network a.a.a.a\nRouter(config-router)# network b.b.b.b\nRouter(config-router)# network c.c.c.c<\/code><\/pre>\n\n\n\n
Donde:<\/p>\n\n\n\n
  • router eigrp<\/em>.- Command to access router configuration mode by assigning the EIGRP routing protocol.<\/li>
  • process-id<\/em>.- Process ID must be configured in all routers that share routing information.<\/li>
  • network.-<\/em> Comando utilizado por el router para habilitar los paquetes EIGRP.<\/li>
  • a.a.a.a <\/em>.- red o host donde se activar\u00e1 EIGRP <\/li><\/ul>\n\n\n\n
    Con los pasos anteriores tendremos a EIGRP funcionando, pero de manera predeterminada, al utilizar el comando network y una direcci\u00f3n de red con clase como 172.16.0.0, todas las interfaces del router que pertenecen a la direcci\u00f3n de red con clase estar\u00e1n habilitadas para EIGRP. Sin embargo, puede haber ocasiones en las que el administrador de red no desee incluir a todas las interfaces dentro de una red al habilitar EIGRP.

    Use the wildcard-mask option with the network command to configure EIGRP to be enabled only on specific interfaces.  All other parameters have the same function as in the configuration at the beginning.

    \u00a0Su configuraci\u00f3n es de la siguiente manera:<\/p>\n\n\n\n
    Router(config)# router eigrp id-proceso\nRouter(config-router)# network a.a.a.a wildcard-mask\nRouter(config-router)# network b.b.b.b wildcard-mask\nRouter(config-router)# network c.c.c.c wildcard-mask<\/code><\/pre>\n\n\n\n
    Donde:<\/p>\n\n\n\n
    • wildcard-mask - Par\u00e1metro para especificar el rango de interfaces donde se habilitar\u00e1 EIGRP.<\/li><\/ul>\n\n\n\n
      La m\u00e1scara wildcard determina qu\u00e9 bits del argumento de la direcci\u00f3n son arbitrarios. Un bit de m\u00e1scara wildcard establecido en 1 significa que el bit de direcci\u00f3n correspondiente puede ser cualquier cosa. Un bit de m\u00e1scara wildcard establecido en 0 significa que el bit de direcci\u00f3n correspondiente debe permanecer.

      Por ejemplo, la red 10.2.2.9 0.0.0.0 significa que todos los bits de 10.2.2.9 importan y habilita EIGRP en una \u00fanica interfaz, una configurada con una direcci\u00f3n IP 10.2.2.9. Por otro lado, la red 10.2.2.9 0.0.0.255 significa que se ignora el \u00faltimo octeto de la direcci\u00f3n y habilita EIGRP en todas las interfaces configuradas con direcciones en el rango 10.2.2.1 - 10.2.2.254<\/p>\n\n\n\n
      Como se obtiene un m\u00e1scara wildcard:<\/span><\/span><\/span><\/strong><\/h4>\n\n\n\n
      Dada la subred 172.16.3.0\/25, imagine que la m\u00e1scara wildcard es lo inverso a una m\u00e1scara de subred o m\u00e1s bien lo restante de dicha m\u00e1scara, ya que a la m\u00e1scara de subred por default 255.255.255.255 le restaremos la m\u00e1scara de subred de la red que queremos publicar, en este caso:<\/span><\/span><\/span><\/p>\n\n\n\n
       <\/span>RESTAMOS<\/span><\/span><\/strong><\/p>\n\n\n\n
      255.255.255.255----------> Default Mask<\/span><\/span><\/span>\n255.255.255.128<\/u>----------> Subnet Mask 172.16.3.0<\/span><\/span><\/span>\n00<\/span><\/span><\/span>0.    0.   0. 127----------> Wildcard Mask<\/span><\/span><\/span><\/strong><\/pre>\n\n\n\n
      Otro ejemplo: Encontrar la m\u00e1scara wildcard de 10.1.0.0\/16<\/span><\/span><\/span><\/p>\n\n\n\n
      RESTAMOS<\/span><\/span><\/span><\/strong><\/p>\n\n\n\n
      255.255.255.255----------> Default Mask<\/span><\/span><\/span><\/span><\/span><\/span>\n255.255.    0.    0<\/u>----------> Subnet Mask<\/span><\/span><\/span> 10.1.0.0<\/span><\/span><\/span>\n00<\/span><\/span><\/span>0.    0.255.255----------> Wildcard Mask<\/span><\/span><\/span><\/strong><\/span><\/span><\/span><\/strong><\/pre>\n\n\n\n
      Ejemplo<\/h4>\n\n\n\n
      Router(config)# router eigrp 10\nRouter(config-router)# network 10.1.1.1 0.0.0.0 \nRouter(config-router)# network 10.99.99.0 0.0.0.255<\/code><\/pre>\n\n\n\n
      EIGRP se habilitar\u00e1 en la interfaz donde est\u00e9 configurada la IP del host 10.1.1.1. Adem\u00e1s, las interfaces que tengan cualquier IP correspondiente a la subred 10.99.99.0\/24.<\/p>\n\n\n\n
      Verifications Commands<\/strong><\/p>\n\n\n\n
      show ip eigrp interfaces [detail] \nshow ip protocols \nshow ip eigrp neighbors \nshow ip eigrp topology [subnet] \nshow ip route [eigrp]<\/code><\/pre>\n\n\n\n
