CCNA LAB No 7: Inter VLAN Routing CONFIGURATION Lab time: 1 session

Students are recommended to read the entire lab requirement before starting The TIP session should only be used for troubleshooting For any problem concerns hardware or losing connectivity, please contact instructor

Topology:

Caution

1 On switch 3550, you must encapsulate the port with dot1q or isl type before turn that port to trunk mode

Task

1 On router Cisco 2600 configure trunk encapsulation and assign VLAN ID for each

subinterfaces

R4(config)#int e0/0 R4(config-if)#no shut R4(config-if)#exit R4(config)#int e0/0.3 R4(config-subif)#encapsulation dot1Q 3 R4(config)#int e0/0.5

R4(config-subif)#encapsulation dot1Q 5

2 Configure two Ethernet subinterfaces on Router R4 to use the last usable IP addresses in subnet 172.0.34.0/24 and 172.0.45.0/24

R4(config)#int e0/0.3

R4(config-subif)#ip address 172.0.34.253 255.255.255.0

R4(config)#int e0/0.5

R4(config-subif)#ip address 172.0.45.253 255.255.255.0

3 Configure Port fa0/4 to turn its mode to trunk mode Match the trunk encapsulation protocol between port fa0/4 and Ethernet subinterface on Router

Sw3550-2(config)#int f0/4

Sw3550-2(config-if)#switchport trunk encapsulation dot1q

Sw3550-2(config-if)#switchport mode trunk

4 Create 2 VLANs on the Switch and add ports in to them as in the above figure

Sw3550-2(config)#vlan 2

Sw3550-2(config)#int f0/2

Sw3550-2(config-if)#switchport mode access

Sw3550-2(config-if)#switchport access vlan 2

We do the same with vlan 5

5 Assign IP addresses for routers’ ethernet 0 interface so that they’re in the same subnet with their corresponding subinterfaces on Router 4

R3(config)#int e0

R3(config-if)#ip address 172.0.34.3 255.255.255.0

R3(config-if)#no shut

R5(config)#int e0

R5(config-if)#ip address 172.0.45.5 255.255.255.0

R5(config-if)#no shut

6 Configure a default route on Router 3 and 5

R3(config)#ip route 0.0.0.0 0.0.0.0 172.0.34.253

R5(config)#ip route 0.0.0.0 0.0.0.0 172.0.45.253

7 Check IP connectivity using Ping command from router R3 to router R5.

Bonus Tasks:

1 Remove any default route on all routers

2 Configure NAT on Router 4 so that R3 can ping R5

3 Try to use all kinds of NAT configuration
