3 CASO DE ESTUDIO 1: CCNP SWITCH

1. Topologa

2. Requisitos

You will configure a group of switches and a router for the International Travel Agency.

The network includes two distribution switches, DLS1 and DLS2, and two access layer

switches, ALS1 and ALS2. External router R1 and DLS1 provide inter-VLAN routing.

Design the addressing scheme using the address space 172.16.0.0/16 range. You can

subnet it any way you want, although it is recommended to use /24 subnets for

simplicity.

3. Solucin al Caso de Estudio

1. Disable the links between the access layer switches.

Para empezar, deshabilitaremos todos los puertos a fin de que no empiecen el proceso

de negociacin spanning-tree hasta haber configurado correctamente VTP y los

correspondientes puertos como troncales y de acceso.

Configuracin:

DLS1(config)#interface range fastEthernet 0/7 - 12

DLS1(config-if-range)#shutdown


DLS2(config-if-range)#shutdown


ALS1(config)#interface range fastEthernet 0/7 - 10

ALS1(config-if-range)#shutdown


ALS2(config-if-range)#shutdown

2. Place all switches in the VTP domain CISCO. Make DLS1 the VTP server and all other

switches VTP clients.

Configuramos todos los switches en el mismo dominio a fin de que compartan las

VLAN aprendidas desde el server (DLS1) para luego asignarlas a los respectivos puertos

de acceso.

Configuracin:

DLS1(config)#vtp mode server

Device mode already VTP SERVER.

DLS1(config)#vtp domain CISCO

Changing VTP domain name from NULL to CISCO

DLS1(config)#end

DLS1#show vtp status

VTP Version : running VTP1 (VTP2 capable)

Configuration Revision : 0

Maximum VLANs supported locally : 1005

Number of existing VLANs : 5

VTP Operating Mode : Server

VTP Domain Name : CISCO

VTP Pruning Mode : Disabled

VTP V2 Mode : Disabled

VTP Traps Generation : Disabled

MD5 digest : 0xD3 0x78 0x41 0xC8 0x35 0x56 0x89 0x97

Configuration last modified by 0.0.0.0 at 0-0-00 00:00:00

Local updater ID is 0.0.0.0 (no valid interface found)


DLS1#

ALS1(config)#vtp mode client

Device mode already VTP CLIENT.

ALS1(config)#vtp domain CISCO

Changing VTP domain name from cisco.com to CISCO

Se repite este ltimo con ALS2 y DLS2.

Una vez terminado de configurar vtp en todos los switches, levantamos las interfaces

para que las VLAN a continuacin puedan ser aprendidas por todos los switches:


DLS1(config-if-range)#no shutdown


DLS2(config-if-range)#no shutdown


ALS1(config-if-range)#no shutdown


ALS2(config-if-range)#no shutdown

3. On DLS1, create the VLANs shown in the VLAN table and assign the names given. For

subnet planning, allocate a subnet for each VLAN.

Configuramos las VLAN solicitadas por el cliente desde DLS1 (vtp mode server) a fin de

que puedan ser aprendidas por el resto de switches.

DLS1#conf t

Enter configuration commands, one per line. End with CNTL/Z.

4. Configure DLS1 as the primary spanning-tree root bridge for all VLANs. Configure DLS2 as

the backup root bridge for all VLANs.

A fin de garantizar que el swith elegido como root sea el ms adecuado en trminos de

recursos, forzaremos uno de los switch de capa 3 a ser el root bridge configurando

todas las VLAN para que formen parte de root primary en DLS1. Luego, realizamos el

mismo procedimiento para que si acaso en ese switch se llega a caer el servicio, el otro

switch de capa 3 (DLS2) sea el root bridge de backup de nuestra red.

5. Configure Fa0/12 between DLS1 and DLS2 as a Layer 3 link and assign a subnet to it.

A continuacin utilizaremos el comando no switchport a fin de deshabilitar las

funciones de capa 2 o switching en esta interface y permitir aprovechar las

funcionalidades de enrutamiento de capa 3.

DLS1(config)#inter fastEthernet 0/12

DLS1(config-if)#no sw

DLS1(config-if)#no switchport

DLS1(config-if)#ip address 172.16.50.10 255.255.255.0

DLS1(config-if)#no shut

DLS1(config-if)#exit

DLS2(config)#inter fastEthernet 0/12

DLS2(config-if)#no switchport

DLS2(config-if)#ip a


DLS2(config-if)#no shutdown


6. Create a loopback interface on DLS1 and assign a subnet to it.

Ahora que hemos configurado VTP y en qu modo van a funcionar algunos puertos,

procedemos a configurar la loopback0. La direccin de red seleccionada para la misma

es:


DLS1(config)#interface loopback 0

DLS1(config-if)#ip add


DLS1(config-if)#no shut


7. Configure the Fa0/11 link between DLS1 and DLS2 as an ISL trunk.

El siguiente paso consiste en configurar la interface fa0/11 entre DLS1 and DLS2 como

ISL trunk. Los comandos son los siguientes:

DLS1(config)#interface fastEthernet 0/11

DLS1(config-if)#switchport trunk encapsulation isl

DLS1(config-if)#switchport mode trunk


DLS2(config)#interface fastEthernet 0/11

DLS2(config-if)#switchport trunk encapsulation isl



8. Statically configure all inter-switch links as trunks.

&

9. Configure all other trunk links using 802.1Q.

A continuacin configuraremos todos los enlaces entre switches como enlaces

troncales mediante el protocolo de encapsulamiento 802.1q. Esto permitir el envo de

paquetes de diferentes VLAN a travs de estos enlaces y no necesariamente un enlace

para cada VLAN (optimizando recursos). La configuracin a seguir es la siguiente:

(config)#interface range fastEthernet 0/7 - 10

(config-if-range)#switchport trunk encapsulation dot1q

(config-if-range)#switchport mode trunk

(config-if-range)#no shutdown

10. Bind together the links from DLS1 to each access switch together in an EtherChannel.

La gran ventaja que ofrece EtherChannel radica en unir o sumar ancho de banda de

diferentes interfaces, de Fast Ethernet por ejemplo, a fin de aumentar la capacidad de

transmisin de nuestros datos. Todos los puertos que van desde DLS1 a cada switch de

acceso (ALS1, ALS2) formarn parte de un canal a fin de duplicar el ancho de banda de

transmisin.


DLS1(config-if-range)#channel-group 3 mode desirable



DLS1(config)#interface port-channel 3

DLS1(config-if)#switchport trunk encapsulation dot1q










DLS2(config-if-range)#exit






DLS2(config-if-range)#exit





ALS1(config-if-range)#channel-group 1 mode desirable

ALS1(config-if-range)#exit

ALS1(config)#interface port-channel 1

ALS1(config-if)#switchport trunk encapsulation dot1q

ALS1(config-if)#switchport mode trunk



















11. Enable PortFast on all access ports.


Configurar un puerto con portfast en aquellos que estamos seguros irn dispositivos

terminales resulta ms eficiente, permitiendo que est listo para usar mucho ms

rpido (a lo mucho 20 seg). De no configurarlo as, este proceso podra tomar hasta 50

seg antes de que el host pueda acceder a la red. Habilitaremos el modo "PortFast"

accediendo mediante consola al Switch y ejecutando los siguientes comandos:

(config)#interface range FastEthernet 0/15 - 17

(config-if)# spanning-tree portfast

(config)#interface range FastEthernet 0/18 - 19


(config)#interface FastEthernet 0/20


(Hay que tener en cuenta que este comando solo puede ser ejecutado en dispositivos

finales de la red).

12. Place Fa0/15 through Fa0/17 on ALS1 and ALS2 in VLAN 10. Place Fa0/18 and Fa0/19 on

ALS1 and ALS2 in VLAN 20. Place Fa0/20 on ALS1 and ALS2 in VLAN 30.

A continuacin asignaremos la respectiva VLAN a los respectivos puertos del switch en

modo de acceso. Este procedimiento ser realizado en los switches a los que se

encuentren conectados dispositivos finales de red y una vez confirmado que hayamos

aprendido las VLAN configuradas por DLS1.

Configuracin:


ALS1(config-if-range)#switchport access vlan 10

ALS1(config-if-range)#switchport mode access











ALS1(config)#interface fastEthernet 0/20

ALS1(config-if)#switchport access vlan 30

ALS1(config-if)#switchport mode access


ALS2(config-if)#switchport access vlan 30

ALS2(config-if)#switchport mode access

13. Create an 802.1Q trunk link between R1 and ALS2. Allow only VLANs 10 and 40 to pass

through the trunk.

Creamos un enlace troncal entre el Switch ALS2 y el R1. Esto permitir la comunicacin

de los hosts que pertenecen a las VLANs 10 y 40 por medio del puerto 0/1 que est

directamente conectado al Router.




ALS2(config-if)#switchport trunk allowed vlan 10,40

R1(config)#interface ethernet 0/0

R1(config-if)#no shutdown


R1(config)#interface ethernet 0/0.10

R1(config-subif)#encapsulation dot1Q 10

R1(config)#interface ethernet 0/0.40


14. Configure R1 subinterfaces for VLANs 10 and 40.

La configuracin de varias interfaces lgicas dentro de una misma interfaz fsica

permite optimizar recursos utilizando un mismo puerto como enlace troncal para el

enrutamiento de VLANs. Para este paso utilizaremos dot1Q como protocolo de

encapsulamiento.

Configuracin:

R1#config t

R1(config)#int fa0/1

R1(config-if)#no shutdown

R1(config-if)#int fa0/1.10

R1(config-subif)#description Red


R1(config-subif)#ip address 172.16.10.1 255.255.255.0

15. Create an SVI on DLS1 in VLANs 20, 30, and 40. Create an SVI on DLS2 in VLAN 10, an SVI on ALS1 in VLAN 30, and an SVI on ALS2 in VLAN 40.

Una SVI es una interfaz virtual que permitir a un conmutador L3 enrutar paquetes

entre VLAN. Otra facilidad que nos ofrece ser podernos conectar a travs de telnet o

SSH al switch utilizando la direccin IP configurada en la SVI. A continuacin se detalla

su configuracin de acuerdo a lo solicitado:

DLS1(config)#interface vlan 20 DLS1(config-if)#ip address 172.16.20.10 255.255.255.0 DLS1(config-if)#no shutdown DLS1(config)#interface vlan 30 DLS1(config-if)#ip address 172.16.30.10 255.255.255.0 DLS1(config-if)#no shutdown DLS1(config)#interface vlan 40 DLS1(config-if)#ip address 172.16.40.10 255.255.255.0 DLS1(config-if)#no shutdown DLS2(config)#interface vlan 10 DLS2(config-if)#ip address 172.16.10.20 255.255.255.0 DLS2(config-if)#no shutdown ALS1(config)#interface vlan 30 ALS1(config-if)#ip address 172.16.30.30 255.255.255.0 ALS1(config-if)#no shutdown ALS2(config)#interface vlan 40 ALS2(config-if)#ip address 172.16.40.40 255.255.255.0 ALS2(config-if)#no shutdown 16. Enable IP routing on DLS1. On R1 and DLS1, configure EIGRP for the whole major network (172.16.0.0/16) and disable automatic summarization.
