Lab 27 Routing between Access layer and Distribution Layer

Objective

• To configure VLAN routing for a layer 3 switch.

Topology

Setting

PC0 and PC2 ar in VLAN1, and PC1 and PC3 are in VLAN2.
Gig1/1 on every access layer is connected to distribution layer.
Distribution layer switch has routing function
IPs for computers have been set up.

Requirments

• Configure the link between switches as trunk
• Configure distribution layer switch to enable routing between VLAN1 and VLAN2.

Steps

On Switch1

Switch>en
Switch#confi t
Switch(config)#vlan 2
Switch(config-vlan)#exit
Switch(config)#int fastEthernet 0/2
Switch(config-if)#switchport access vlan 2
Switch(config)#int gigabitEthernet 1/1
Switch(config-if)#switchport mode trunk
Switch(config-if)#

On Switch2

Switch>en
Switch#confi t
Switch(config)#vlan 2
Switch(config-vlan)#exit
Switch(config)#int fastEthernet 0/2
Switch(config-if)#switchport access vlan 2
Switch(config)#int gigabitEthernet 1/1
Switch(config-if)#switchport mode trunk
Switch(config-if)#

On Switch0

Switch>en
Switch#confi t
Switch(config)#vlan 2
Switch(config)#interface gigabitEthernet 0/1
Switch(config)#switchport trunk encapsulation dot1q
Switch(config-if)#switchport mode trunk
Switch(config-if)#exit
Switch(config)#interface gigabitEthernet 0/2
Switch(config)#switchport trunk encapsulation dot1q
Switch(config-if)#switchport mode trunk
Switch(config)#interface vlan 1
Switch(config-if)#ip address 192.168.0.1 255.255.255.0
Switch(config-if)#no sh
Switch(config-if)#exit
Switch(config)#interface vlan 2
Switch(config-if)#ip address 192.168.1.1 255.255.255.0
Switch(config-if)#no sh
Switch(config-if)#

On PC3, ping PC0
