Trunk øvelse

For at fuldføre denne øvelse skal VLAN øvelse være udført. Dette er en fortsættelse af denne øvelse.

Opgave 1: Tilslutning af Router

Der anvendes en Trunk port mellem Switch 1 port 23 og en 1841 Router fastethernet 0/0 som vis i tegningen herunder.

Router tilføjet til switch1

Opgave 2: Oprettelse af trunkport på switch

Port 23 på Switch 1 skal konfigureres som en Trunk port. Se i VLAN øvelsen hordan dette gøres.

Opgace 3: Fastethernet 0/0 lukkes op

Opgave 4: VLAN 1 oprettes

VLAN 1 er ikke anvendt, men tildeles alligevel en IP adresse i dette eksempel.

Router><input>enable</input>
Router#<input>configure terminal</input>
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#<input>interface fastethernet 0/0.1</input>
Router(config-subif)#<input>encapsulation dot1Q 1 native </input>
Router(config-subif)#<input>ip address 10.1.1.1 255.255.255.0</input>
Router(config-subif)#<input>exit</input>

Opgave 5: VLAN 100 oprettes

Router><input>enable</input>
Router#<input>configure terminal</input>
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#<input>interface fastethernet 0/0.100</input>
Router(config-subif)#<input>encapsulation dot1Q 100</input>
Router(config-subif)#<input>ip address 192.168.1.1 255.255.255.0</input>
Router(config-subif)#<input>exit</input>

Opgave 6: VLAN 200 oprettes

• PC1's IP adresse ændres fra 192.168.1.11 til 192.168.200.11
• PC3's IP adresse ændres fra 192.168.1.13 til 192.168.200.13

Router><input>enable</input>
Router#<input>configure terminal</input>
Enter configuration commands, one per line.  End with CNTL/Z.

Router(config-subif)#<input>exit</input>

Opgave 7: VLAN 300 oprettes

Router><input>enable</input>
Router#<input>configure terminal</input>
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#<input>interface fastethernet 0/0.300</input>
Router(config-subif)#<input>encapsulation dot1Q 300</input>
Router(config-subif)#<input>ip address 172.16.0.1 255.255.0.0</input>
Router(config-subif)#<input>exit</input>

Yderligere test

Prøv følgende kommandoer

• show ip route
• show running-config

Opgave 9: Konfiguration af PC'ere

• Kan PC'erne pinge hinanden?
  • Hvis ikke - hvorfor ikke.
