Un poco de Politica. Tlajomulco
No lo puedo creer, un tipo que a todas luces se ve deshonesto, que basta un googlazo para descubrir su lado oscura, gana una eleccion basada en puras mentiras, ademas no entiendo como no fue demandad0 por que gasto una cantidad exhorbitante de recursos, este cuate, con toda desfachatez es el diputado Enrique Alfaro, ahhh pobre de nuestra gente.

Para esta practica se hizo lo siguiente
Armó la maqueta
verifico la conectividad (ping pc-r1,r-pc, r-r)
habilitar el RIP
Se habilito el Show IP Route
habilitar RIP V2
verificar conectividad E2E
Existen distintyos tipos de configuración y uno de ellos es el lazo de ruteo que tiene como ventaja el tiempo de convergencia
El estado de enlace tiene las desventajas de qu require muchos recursos de cpu memoria y ancho de banda y cada router genera su propia tabla de ruteo-
OSPF= open shortest path first.
Este se maneja por areas donde por area puede haber dentre 20 a 30 maquinas porque menos a este no tiene razon de ser
Para configurar OSPF

practica 5
PRACTICA 5 RIP REDES AVANZADASEn esta práctica fue muy similar a las realizadas con los protocolos RIP y RIP2 con la diferencia de que ahora utilizamos el protocolo de enrutamiento OSPF (Open Shortest Path First) que su función es calcular la ruta más corta posible
Diagrama de conexión
Diagrama de conexión
Una vez configurado el serial para conectarnos con el router, además del puerto ethernet 0 para la pc, procedimos a configurar el protocolo de enrutamiento OSPF, para el cual nos fuimos a config y posteriormente tecleamos "router OSPF 1" (cave mencionar que podemos haber puesto de 1 a 255). Lo interesante aquí es que ahora al momento de configurar las marcaras había que hacerlo al revés, por ejemplo: si se tenía 255.255.255.252 había que poner 0.0.0.3
Después se hicieron ping's a las pc y procedió a ver la configuración de las redes en OSPF.Para esto utilizamos el comando "show ip ospf database router". el cual nos mostraba toda la configuración de las conexiones
En un detalle se ve que si no hay tabla de ruteo no hay conexión.
El rip se refresca cada 30n segundos el cual ofrece una eficiencia solo en máximo a los 15 saltos.

El objetivo de esta práctica es comunicar varias computadoras y routers por medio del protocolo RIP, es cual nos va a permitir comunicarnos con los dispositivos vecinos por medio de la tabla de enrutamiento que este protocolo obtiene.
Diagrama.
Este diagrama muestra la configuración física de lo equipos conectados cada uno a sus respectivos routers. A partir de esto se les asignaron direcciones IP para lograr la comunicación entre los equipos y se les asignaron las siguientes direcciones.

Procedimiento.
En primer lugar debemos tener ya la comunicación entre nuestro propio Router con nuestra propia PC, para esto se hará la configuración que hicimos en la práctica pasada, es decir la práctica 3.
Una vez que ya esta funcionando el enlace de nuestros dos dispositivos a través del puerto Ethernet0 del Router, debemos hacer los enlaces con los demás routers para esto utilizaremos los puertos seriales, que son serial0 y serial1.
Nota: Nosotros somos el equipo del Router 1 y por tal motivo vamos a hacer solo un enlace, que será con el Router 2.
Para poder hacer la configuración del puerto Serial0 tenemos que estar, también en este caso, en el modo de configuración. Para esto utilizaremos los comando de enable para acceder al modo privilegiado, y una vez ahí utilizaremos el comando configure, para acceder al modo de configuración. Recordemos que nuestro Router lleva por nombre “canaca”, por tal motivo el promp aparecerá de la siguiente manera: canaca(config)# una vez que aparece así entonces empezaremos a configurar y escribiremos la siguiente lista de comandos:
canaca(config)#interface serial0
canaca(config-if)#ip address 148.202.23.1 255.255.255.0
canaca(config-if)#clock rate 64000
canaca(config-if)#no shutdown
Una vez escrito esta lista de comandos entonces podremos darnos cuenta que efectivamente se realizo la configuración como se quería, para esto se utilizara el comando show config, entonces se visualizara en la pantalla el siguiente texto:
canaca#
%SYS-5-CONFIG_I: Configured from console by console
canaca#
%LINK-3-UPDOWN: Interface Serial0, changed state to down
canaca#write

[OK]
canaca#show config

line con 0
password hola
line aux 0
line vty 0 1
login
line vty 2
password 5678
login
line vty 3 4
login
!
end
Hasta este momento nosotros ya tenemos configurado el puerto por medio del cual nos comunicaremos con los demás integrantes de la red.
Si en este momento hacemos ping con los demás elementos de la red nos daremos cuenta de que a pesar de ya esta conectados físicamente con todos los demás Routers no podremos aun establecer la comunicación con ellos debido a que no se cuenta con la tabla de enrutamiento que el Protocolo RIP crea, es por eso que hasta el momento no podremos enviar ningún tipo de información.
Si en este momento escribimos en el promp el comando show IP route obtendremos en pantalla la tabla de enrutamiento de los equipos con los cuales ya nos es posible empezar a intercambiar información, lo veremos en el siguiente código:
canaca#en show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default
U - per-user static route
Gateway of last resort is not set
148.202.0.0/16 is subnetted, 2 subnets
C 148.202.23.0 is directly connected, Serial0
C 148.202.34.0 is directly connected, Ethernet0
Como podemos ver solo podemos comunicarnos con nuestro equipo y no con los demás integrantes de la red aunque físicamente ya haya conexión.
Es en este momento en el cual escribiremos la siguiente secuencia de comandos para establecer la tabla de enrutamiento de la red.
canaca(config)#router rip
canaca(config-router)#network 148.202.23.0
canaca(config-router)#network 148.202.23.0 34.0
canaca(config-router)#^Z
Con esto estamos avisando a los elementos de la red que estamos listos para empezar a intercambiar información. Es importante que esta secuencia de comando la realicen todos y cada uno de los integrantes de la red para saber quien, aparte de nosotros, esta también listo para la comunicación.
Cuando todos los elementos de la red lo hayan hecho entonces escribiremos nuevamente el comando show ip route para que nos muestre nuevamente la tabla de enrutamiento que obtuvo al hacer “el barrido” de la red para ver quienes están listos, lo veremos en el siguiente texto:
canaca#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default
U - per-user static route
Gateway of last resort is not set
148.202.0.0/16 is subnetted, 9 subnets
R 148.202.26.0 [120/3] via 148.202.23.2, 00:00:02, Serial0
R 148.202.24.0 [120/1] via 148.202.23.2, 00:00:02, Serial0
R 148.202.25.0 [120/2] via 148.202.23.2, 00:00:03, Serial0
C 148.202.23.0 is directly connected, Serial0
R 148.202.38.0 [120/4] via 148.202.23.2, 00:00:03, Serial0
R 148.202.36.0 [120/2] via 148.202.23.2, 00:00:03, Serial0
R 148.202.37.0 [120/3] via 148.202.23.2, 00:00:03, Serial0
C 148.202.34.0 is directly connected, Ethernet0
R 148.202.35.0 [120/1] via 148.202.23.2, 00:00:03, Serial0
Como vemos ahora la tabla de enrutamiento es mayor pues ya incluye prácticamente a toda la red, es decir que ya podemos establecer comunicación con cualquiera de ellos.
Una forma de comprobar que efectivamente ya podemos entablar comunicación haremos ping con todos los integrantes.
canaca#ping 148.202.35.2
canaca#ping 148.202.36.1
canaca#ping 148.202.37.1
canaca#ping 148.202.38.3

SECCION D01
PRACTICA 1
DISPOSITIVOS DE INTERCONEXION DE RED
OBJETIVO:
Reconocer las diferentes arquitecturas de los dispositivos de interconexión de redes.
DESARROLLO: Identificar y conocer los componentes internos y externos de un Hub, un Router y un Switch-HUB.
HUB.
Es un dispositivo que permite centralizar el cableado de una RED conocido tambien con el nombre de concentrador o hub, y funciona repitiendo cada paquete de datos en cada uno de los puertos con los que cuenta, excepto en el que ha recibido el paquete, de forma que todos puntos tienen acceso acceso a los datos.
ROUTER.
Un Router es un enrutador, elemento que marca el camino mas adecuado para la transmisión de mensajes en una red completa, por ejemplo Internet tiene miles de estos Router.Este toma como por decirlo el mejor camino para enviar los datos dependiendo del tipo de protocolo que este cargado.El Router casi es un computador, claro que no tiene Mouse ni Monitor, pero si tiene procesador. El Router que va hacer de DCE es el que como por decirlo el que administra, es el mas robusto, tiene mas procesadores y mucha mas capacidad en sus respectivas memorias.
SWITCH.
Caracteristicas.Un switch o conmutador es un hub mejorado: tiene las mismas posibilidades de interconexión que un hub (al igual que un hub, no impone ninguna restricción de acceso entre los ordenadores conectados a sus puertos). Sin embargo se comporta de un modo más eficiente reduciendo el tráfico en las redes y el número de colisiones.El switch que se vio fue un MMAC-3 FND (Multimedia Access Center).Cuenta contaba con 7 puertos, 2 microcontroladores Intel I960 este fue muy popular y fue el primero con tegnologia RISC. Un microcontrolador estaba destinado como administrador y el otro para la regeneracion de trama.Sus funciones:Un switch no difunde las tramas Ethernet por todos los puertos, sino que las retransmite sólo por los puertos necesarios. Por ejemplo, si tenemos un ordenador A en el puerto 3, un ordenador B en el puerto 5 y otro ordenador C en el 6, y enviamos un mensaje desde A hasta C, el mensaje lo recibirá el switch por el puerto 3 y sólo lo reenviará por el puerto 6 (un hub lo hubiese reenviado por todos sus puertos).Cada puerto tiene un buffer o memoria intermedia para almacenar tramas Ethernet.Puede trabajar con velocidades distintas en sus ramas (autosensing): unas ramas pueden ir a 10 Mbps y otras a 100 Mbps.Suelen contener 3 diodos luminosos para cada puerto: uno indica si hay señal (link), otro la velocidad de la rama (si está encendido es 100 Mbps, apagado es 10 Mbps) y el último se enciende si se ha producido una colisión en esa rama.
El router que nos toco analizar el Cisco IGS-R
Contiene una fuente de poder
Contiene un procesador Motorola MC6802 ORP16E a 8bits
Memoria RAM Motorola MC91000AS
4 Módulos de 9
Memoria ROM EPRO M27C00
8 Módulos
1 OSC 3.68MGH para puerto serial
2OSC 20X10^3 MGH puerto Ethernet
1OSC 3.2X10^6 MGH para el Microprocesador
MEMORIA FLASH Configuración BENCHMARQ
MICROCODIGO -AM7990PCI -MK5025P-10 1 swich interprete 1Interface Ethernet - Puerto local (LAN) 1Interface Serial (WAN)
Conclusiones. Con respecto a esta práctica estuvo interesante ya que diferenciamos bien entre un hub, switch y un router, el conocerlos tanto por el exterior como en el interior, diferenciar con que componentes cuentan, lo malo es que no hay muchos equipos y los que hay están muy obsoletos. Estoy sorprendido de los aparatos tan viejitos que usamos. Ojalá se le de mejor equipo a una clase con tanta trascendencia el el mercado laboral.
