3 - VLANS PARTE 3

VLANS PARTE 3

Continuaremos a configuração de vlans mas agora usaremos um trunk para que os computadores dos dois switches possam se comunicar

.

Equipamentos necessários:

1 Router 1941

Topologia:

Usando a topologia passada iremos adicionar um roteador para fazer roteamento inter vlan pois os switches que adicionamos são L2.

No Router0:

interface GigabitEthernet0/1
no ip address
duplex auto
speed auto
!
interface GigabitEthernet0/1.10
encapsulation dot1Q 10
ip address 192.168.10.1 255.255.255.0
!
interface GigabitEthernet0/1.20
encapsulation dot1Q 20
ip address 192.168.20.1 255.255.255.0
!
interface GigabitEthernet0/1.30
encapsulation dot1Q 30

ip address 192.168.30.1 255.255.255.0

No Switch0:
interface GigabitEthernet0/2
switchport trunk allowed vlan 10,20,30

switchport mode trunk


No Switch0 alteramos os ips das interfaces vlans 10,20 e 30.

interface Vlan10
description Vlan10
ip address 192.168.10.253 255.255.255.0
!
interface Vlan20
description Vlan20
ip address 192.168.20.253 255.255.255.0
!
interface Vlan30
description Vlan30
ip address 192.168.30.253 255.255.255.0

!

No Router0 precisamos verificar se o CEF está ativado. Se não estiver, precisamos ativar no modo de configuração para otimizar o encaminhamento de pacotes.

Router0#conf t

Router0(config)#ip cef

A partir do PC0 iremos pingar os outros computadores e o gateway para testar o roteamento inter vlan:
