INTER VLAN ROUTER ON STICK
Untuk menghubungkan VLAN yang berbeda membutuhkan perangkat layer 3 baik itu router atau switch layer3. Cara pertama adalh dengan menggunakan 1 interface teknik ini disebut Router On Stick. Kekurangan dari teknik ini akan terjadi solution domain karna hanya menggunakan 1 interface.
Ada 2 trunking protocol yang bisa digunakan :
a. ISL (cisco proprietary)
b. IEEE 802.IIQ (dot1Q)
Cara konfigurasi
Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#interface FastEthernet0/0
Router(config-if)#no shutdown
Router(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
Router(config-if)#exit
Router(config)#exit
Router#
%SYS-5-CONFIG_I: Configured from console by console
Router#exit
Router con0 is now available
Press RETURN to get started.
Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#int
Router(config)#interface fa
Router(config)#interface fastEthernet 0/0.100
Router(config-subif)#
%LINK-5-CHANGED: Interface FastEthernet0/0.100, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0.100, changed state to up
Router(config-subif)#en
Router(config-subif)#encapsulation do
Router(config-subif)#encapsulation dot1Q 100
Router(config-subif)#ip address 100.100.100.1 255.255.255.0
Router(config-subif)#exit
Router(config)#int
Router(config)#interface fa
Router(config)#interface fastEthernet 0/0.200
Router(config-subif)#
%LINK-5-CHANGED: Interface FastEthernet0/0.200, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0.200, changed state to up
Router(config-subif)#en
Router(config-subif)#encapsulation d
Router(config-subif)#encapsulation dot1Q 200
Router(config-subif)#ip address 200.200.200.1 255.255.255.0
Router(config-subif)#exit
Router(config)#do wr
Building configuration...
[OK]
Router(config)#
Dan haslinya seperti ini ketika di ping 100.100.100.2 ke 200.200.200.2
