Create Vlan dengan Trunk port yang berbeda di Cisco

sebelum kita create vlan di cisco(router/switch), ada baiknya mengetahui apa vlan itu, vlan atau virtual lan adalah sub interface / inteface logical yang dibuat untuk menambah alokasi inteface tanpa menambah interface secara fisik. dalam tulisan ini berikut gambar topologinya :





Konfigurasi port fa 0/1 dimasukan kedalam vlan 101 :
SWITCH-A(config-if)#switchport mode access
SWITCH-A(config-if)#switchport access vlan 101
konfigurasi port fa 0/2 dimasukan kedalam vlan 200 :
SWITCH-A(config-if)#switchport mode access
SWITCH-A(config-if)#switchport access vlan 200

Cekk konfirugasi vlan : SWITCH-A#show vlan


Create port trunk untuk vlan 101 di port fa 0/24 :
SWITCH-A(config)#interface fastEthernet 0/24
SWITCH-A(config-if)#switchport mode trunk
SWITCH-A(config-if)#switchport trunk allowed vlan 101

create port trunk untuk vlan 200 di port fa 0/22 :
SWITCH-A(config)#interface fastEthernet 0/22
SWITCH-A(config-if)#switchport mode trunk
SWITCH-A(config-if)#switchport trunk allowed vlan 200

setting vlan di Router0 :
 Router0#configure terminal
Router0(config)#interface fastEthernet 0/0.101
Router0(config-subif)#encapsulation dot1Q 101
Router0(config-subif)#ip address 192.168.101.1 255.255.255.248

setting vlan di Router1 :
Router1#configure terminal
Router1(config)#interface fastEthernet 0/0.200
Router1(config-subif)#encapsulation dot1Q 200
Router1(config-subif)#ip address 192.168.200.1 255.255.255.248

Simpan Konfiguransi di Switch A, Router 0 dan Router 1 :
SWITCH-A#write memory

konfigurasi ip di masing-masing PC :
