CCNA ICND1 Lab3 - Routing Between VLANs

Suppose that there are four VLANs. To realize communication between them, you need four LAN ports. A router with four ports is expensive, so we use one port to realize communication between the four VLANs. The following lab is an example of two VLANs.

Topology:

Lab Requirements:

1. Segment the switch into two VLANs.

2. Port fa0/2 is in VLAN2 and Port fa0/3 is in VLAN3.

3. Make the link between Port f0/1 of the switch and Port fa0/0 of the router a trunk link.

4. Realize the communication between P4S-host1 and P4S-host2.

Lab Process:

(Switch Configuration)

P4S-Switch#vlan database

P4S-Switch (vlan)#vlan 2 name pass4sure2

P4S-Switch (vlan)#vlan 3 name pass4sure3

P4S-Switch (vlan)#exit

P4S-Switch #configure terminal

P4S-Switch (config)#interface fastethernet0/2

P4S-Switch (config-if)#switchport access vlan 2

P4S-Switch (config)#interface fastethernet0/3

P4S-Switch (config-if)#switchport access vlan 3

P4S-Switch (config)#interface fastethernet0/1

P4S-Switch (config-if)#switchport trunk encapsulation isl

(Router Configuration)

P4S-Router(config)#interface fa0/0

P4S-Router(config-if)#duplex full fa0/0

P4S-Router(config-if)#no shutdown

P4S-Router(config-if)#exit

P4S-Router(config-if)#interface fa0/0.1

P4S-Router(config-if)#encapsulation isl

P4S-Router(config-if)#ip address 192.168.1.1 255.255.255.0

P4S-Router(config-if)#exit

P4S-Router(config-if)#interface fa0/0.2

P4S-Router(config-if)#encapsulation isl

P4S-Router(config-if)#ip address 192.168.2.1 255.255.255.0

P4S-Router(config-if)#exit
