Practica 2 - Redes de Computadoras 1

De acuerdo al enunciado de la practica, para las direcciones IP hay una "X" la cual debe de ser reemplazada por la sumatoria de los últimos dos números del carnet, mas el numero del grupo. En este caso: X = 1 + 1 + 12 = 14

Quedando las direcciones IP en VPC's de la siguiente manera:

Topología Dirección IP Gateway
1 192.168.141.10/24 192.168.141.1
2 192.168.141.20/24 192.168.141.1
3 192.168.142.10/24 192.168.142.1
4 192.168.142.20/24 192.168.142.1
5 192.168.143.10/24 142.168.143.1
6 192.168.143.20/24 142.168.143.1

Dirección IP en routers:

Topología Dirección de RED Primera Dirección Asignable Gateway
R1-R2 172.141.0.0/16 172.141.0.1 N.A.
R1-R3 172.142.0.0/16 172.142.0.1 N.A.
R3-R2 172.143.0.0/16 172.143.0.1 N.A

Configuración de puertos en Switch para colocar en Modo Truncal

modotrunk

como se puede observar el puerto cero esta en modo dot1q (trunk), esto debido a que en ese puerto se conecta al router, y esto se hace para cada switch en el puerto que esta conectado al router, en esta practica el puerto e0 de cada switch se configuro en modo trunk para la conexión con el router.

Configuración del modo FastEthernet y puertos serial en cada Router

conf puerto serial y fastethernet

Conexion entre Routers

  • R1 - R2 ---- S1/0 - S2/0
  • R1 - R3 ---- S1/1 - S3/0
  • R2 - R3 ---- S2/1 - S3/1
