Inter VLAN switch layer 3

INTER VLAN SWITCH LAYER 3

Untuk menghubungkan antar VLAN dibutuhkan suatu perangkat Layer 3, baik itu Router atau Switch
Layer 3. Kalau sebelumnya menggunakan Router on Stick. Kali ini kita akan menggunakan switch layer 3, Inilah kelebihan Cisco kalau switch yang lain bekerja pada Layer 2, Sedangkan switch Cisco dapat bekerja pada Layer 3 dan menjalankan Routing. Namun uuntuk Routing yang lebih luas lebih dianjurkan menggunakan Router.

  

 

Konfigurasi Switch Layer 3

1.      Memberi nama vlan 10

 

Switch(vlan)#vlan 10 name guru

VLAN 10 modified:

Name: guru

Switch(vlan)#vlan 20 name siswa

VLAN 20 modified:

Name: siswa

Switch(vlan)#

2.      Memberi IP Address

Switch(config-if)#int vlan 10

Switch(config-if)#

%LINK-5-CHANGED: Interface Vlan10, changed state to up

Switch(config-if)#ip address 10.10.10.1 255.255.255.0

Switch(config-if)#int vlan 20

Switch(config-if)#

%LINK-5-CHANGED: Interface Vlan20, changed state to up

Switch(config-if)#ip address 20.20.20.1 255.255.255.0

Switch(config-if)#int fa0/1

Switch(config-if)#switchport mode access

Switch(config-if)#switchport access vlan 10

Switch(config-if)#

%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan10, changed state to up

Switch(config-if)#int fa0/2

Switch(config-if)#switchport mode access

Switch(config-if)#switchport access vlan 10

Switch(config-if)#int fa0/3

Switch(config-if)#switchport mode access

Switch(config-if)#switchport access vlan 20

Switch(config-if)#

%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan20, changed state to up

Switch(config-if)#int fa0/4

Switch(config-if)#switchport mode access

Switch(config-if)#switchport access vlan 20

Switch(config-if)#

3.      Routing switch

Switch(config)#ip routing
