    # [RC1] PROYECTO 2 ###### Integrantes > Ronald Alexandro Castro Perez - 201800699 > José Ottoniel Sincal Guitzol - 201801375 > Carlos Esteban Vivar Torres - 201801597 ## Requisitos y Compatibilidad GNS3 es una plataforma que permite simular topologías de red con imágenes de vendors como Cisco y Juniper, entre otros. A continuación se muestran los requerimientos para la instalación del software. ### Compatibilidad * Windows 7 SP1 (64 bit) * Windows 8 (64 bit) * Windows 10 (64 bit) * Windows Server 2012 (64 bit) * Windows Server 2016 (64 bit) * Distribuciones basadas en Ubuntu (solo 64 bits) * Distribuciones basadad en Debian (solo 64 bits) ### Requisitos de GNS3 | Item | Requisito | | ----------------- | ------------------------------------------------------------ | | Sistema Operativo | Los mencionados en el apartado anterior | | Procesador | 2 o más núcles lógicos | | Virtualización | Se requieren extensiones de virtualización. Es posible que deba habilitar esto a través del BIOS de su computadora. | | Memoria | 4 GB RAM | | Espacio en disco | 1GB de espacio disponible (la instalación es < 200MB). | | Otros | Es posible que necesite almacenamiento adicional para su sistema operativo e imágenes de los equipos. | ### Detalle de los equipos utilizados #### Topología 1 - **Sistema Operativo**: Zorin OS 16 (basada en Ubuntu) - **Procesador**: Intel® Core™ i5-7200U CPU @ 2.50GHz × 4 - **Memoria**: 8 GB RAM - **Disco**: 1 TB #### Topología 2 - **Sistema Operativo**: Windows 10 (64 bits) - **Procesador**: Intel® Core™ i7 - **Memoria**: 16 GB RAM - **Disco**: 2 TB #### Topología 3 - **Sistema Operativo**: Windows 10 (64 bits) - **Procesador**: Intel® Core™ i5-10300H - **Memoria**: 8 GB RAM - **Disco**: 256 GB SSD NVME ## Carga de archivos de configuracion Los archivos de configuracion se presentan en el siguiente repositorio de git: https://github.com/joseSincal/REDES1-Proyecto2 Para hacer la carga debemos. 1. Copiar el contenido del archivo de configuracion ![](https://i.imgur.com/H5QnzyT.png) 2. Pegar el contenido dentro de la consola del dispositivo correspondiente haciendo click derecho o ctl+shift+V. ![](https://i.imgur.com/5wnRlIG.png) # Cálculos ### Topología 1 > Número de subredes: 4 | Subred | Equipos pertenecientes | | ------ | ---------------------- | | 1 | R3, R4, R5 y R6 | | 2 | R3, R4, R5 y R7 | | 3 | R3 y R6 | | 4 | R5 y R7 | > Red: 10.10.0.0/16 Mediante el el argoritmo de FLSM se realizarón los siguientes cálculos, esto con el fin de realizar de manera eficiente la conexión de toda la red. #### Cálculo de bits de subredes necesarias Dado que el prefijo a útilizar es **/16**, estó nos indica que se utilizaran 16 bits para la parte de red y 16 bits para la parte de los hosts. ``` 11111111.11111111.00000000.00000000 ⟹ 255.255.0.0 ``` Para poder determinar los bits a tomar para la parte de host de utilizó la siguiente expresión: **2^n ≥ 4**, en donde *4* representa la cantidad de subredes que deseamos crear. Al realizar el respectivo despeje, obtenemos que ***n =~ 2***, lo cual nos indica que tomaremos 2 bits de la parte de hosts, el cual corresponderá a nuestra nueva mascara de red. ``` 2^2 = 4≥4 ⟹ n=2 ``` Ya tomados nuestros 2 bits de la parte de host nuestra nueva máscará será: **/18** ``` 11111111.11111111.11000000.00000000 ⟹ 255.255.192.0 ``` #### Obtener subredes Dados los *n* bits obtenidos en el paso anterior se utiliza una serie de combinación entre esos bits para poder obtener la red de cada subred. En este caso los bits a combinar serán: **00**, **01**,**10** y **11**, esto ya que solo son 2 bits los que podemos tomar de la parte de los hosts. | Subred | Dirección (binario) | Dirección | | ------ | --------------------------- | --------------- | | 1 | 10.10.**00**000000.00000000 | 10.10.**0**.0 | | 2 | 10.10.**01**000000.00000000 | 10.10.**64**.0 | | 3 | 10.10.**10**000000.00000000 | 10.10.**128**.0 | | 4 | 10.10.**11**000000.00000000 | 10.10.**192**.0 | #### Cálculo de hosts por cada subred El número de hosts viene dado por la formula siguiente: **H=2^n−2**, donde *n* es el número de bits que se encuentran libres de la parte de hosts; en nuestro caso usaremos **14** ya que los bits iniciales eran 16 menos los 2 que se utilizaran para la obtención de las subredes nos da como resultado 14 (16-2). ``` H = 2^14−2 = 16382 ``` Ahora sabemos la cantidad de hosts que contendrá cada subred, ahora procedemos a obtener el rango de direcciones para cada subred, el cual se obtiene dela combinación de los bits de hosts que van desde **00000000000001** hasta **11111111111110**, estas direcciones corresponden al primer host y al último. **Nota**: para la dirección de broadcast se deben hacer 1 todos los bits de la parte del host | Subred | Salto | **Network** | **Mask** | P.D asignable | **U.D asignable** | Broadcast | **Host totales** | **Cantidad de host** | | ------ | ----- | -------------- | ------------- | ------------- | ----------------- | ------------- | ---------------- | -------------------- | | 1 | 64 | 10.10.0.0/18 | 255.255.192.0 | 110.10.0.1 | 10.10.63.254 | 10.10.63.255 | 16382 | 4 | | 2 | 128 | 10.10.64.0/18 | 255.255.192.0 | 10.10.64.1 | 10.10.127.254 | 10.10.127.255 | 16382 | 4 | | 3 | 192 | 10.10.128.0/18 | 255.255.192.0 | 10.10.128.1 | 10.10.191.254 | 10.10.191.255 | 16382 | 2 | | 4 | 255 | 10.10.192.0/18 | 255.255.192.0 | 10.10.192.1 | 10.10.255.254 | 10.10.255.255 | 16382 | 2 | --- ### Topología 2 ### Total Hosts: 190 - Recursos humanos: 21 - Contabilidad: 8 - Ventas: 93 + 93*(32/100) = 123 - Informatica: 31 + 31*(18/100) = 37 ### Subredes | Subred | Vlan | Nombre | Numero de host | | :----: | :---: | :-------------: | :------------: | | 1 | 30 | ventas |123| | 2 | 40 | informatica |37| | 3 | 10 | rhumanos |21| | 4 | 20 | contabilidad |8| ### Subnetting de Direccion 192.168.10.0/24 con VLSM Identificamos la mascara de subred actual . /24 > 11111111.11111111.11111111.00000000 #### Calculo numero de bits por parte de host Utilizamos la formula > 2^n - 2 >= H* Donde: - n: numero de bits - H: numero de hosts Para la primera subred tenemos el siguiente calculo. > 2^7 - 2 = 126 >= 123; n = 7 #### Calcuo de numero de bits de subred Utilizamos la formula > R = (32 - p) - n Donde: - n: numero de bits de host - H: prefijo de nuestra red (/24) Para la primera subred tenemos el siguiente calculo. > R = (32 - 24) -7 = 1 #### Nueva Mascara de subred Calculamos el nuevo prefijo, esto sumandole **R** al prefijo original > 24 + 1 = 25 Obtenemos la nueva mascara de subred. > 11111111.11111111.**11111111.1**0000000 (/25) > > -> 255.255.255.128 #### Calculo de salto de red . Es la diferencia de 256 y el ultimo octeto de la nueva red. > S = 256 - 128 = 128 ### Demas Subredes | Ventas | | |:--------------:|:--------------------------------------------- | | Mascara actual | 11111111.11111111.11111111.00000000 | | Numero de host | 2^7 - 2 = 126 >= 123; n = 7 | | Nueva mascara | 11111111.11111111.**11111111.1**0000000 (/25) | | Salto de red | 256 - 128 = 128 | | Informatica | | |:--------------:|:--------------------------------------------- | | Mascara actual | 11111111.11111111.11111111.00000000 | | Numero de host | 2^6 - 2 = 62 >= 37; n = 6 | | Nueva mascara | 11111111.11111111.**11111111.11**000000 (/26) | | Salto de red | 256 - 64 = 192 | | Recursos humanos | | |:----------------:|:--------------------------------------------- | | Mascara actual | 11111111.11111111.11111111.00000000 | | Numero de host | 2^5 - 2 = 30 >= 21; n = 5 | | Nueva mascara | 11111111.11111111.**11111111.111**00000 (/27) | | Salto de red | 256 - 32 = 224 | | Contabilidad | | |:--------------:|:--------------------------------------------- | | Mascara actual | 11111111.11111111.11111111.00000000 | | Numero de host | 2^4 - 2 = 14 >= 8; m = 4 | | Nueva mascara | 11111111.11111111.**11111111.1111**0000 (/28) | | Salto de red | 256 - 16 = 240 | | VLAN | Salto | Network | Mask | P.D asignable | U.D asignable | Broadcast | Host totales | Cantidad de host | | :---: | :---: | -------------- | --------------- | -------------- | -------------- | -------------- | :----------: | :--------------: | | 30 | 128 | 192.168.10.0 | 255.255.255.128 | 192.168.10.1 | 192.168.10.126 | 192.168.10.127 | 126 | 123 | | 40 | 192 | 192.168.10.128 | 255.255.255.192 | 192.168.10.129 | 192.168.10.190 | 192.168.10.191 | 62 | 37 | | 10 | 224 | 192.168.10.192 | 255.255.255.224 | 192.168.10.193 | 192.168.10.222 | 192.168.10.223 | 30 | 21 | | 20 | 240 | 192.168.10.224 | 255.255.255.240 | 192.168.10.225 | 192.168.10.238 | 192.168.10.239 | 14 | 8 | ## Comandos ### Red Wan - Topología 1 #### Asignación de IP's en routers ``` > configure terminal > interface [PUERTO] # donde [PUERTO] es la interfaz en donde deseamos realizar dicha configuración.
