Nah Skema jaringan di atas digunakan untuk implemantasi contoh kasus
dimana tiap lantai ada komputer dengan departemen yang sama. Kita
hubungkan komputer-komputer itu dangan VLAN. Nah disini saya setting
vlan2 untuk keuangan,vlan3 untuk produksi dan vlan4 untuk training.
masing-masing ip VLAN pada router yang dipakai sebagai gateway di tiap komputer departemen masing-masing yaitu :
vlan2 192.168.2.200 subnet 255.255.255.0
vlan3 192.168.3.200 subnet 255.255.255.0
vlan4 192.168.4.200 subnet 255.255.255.0
untuk penomoran ip tiap komputer vlan x 192.168.x.y dimana x= no
vlan yang dipakai dan y bernilai 1-5 sesuai no komputer pada skema
jaringan di atas dan gateway sesuai ip vlan diatas
pada tiap switch saya buat port 1,2,3 vlan2,port 4,5,6 vlan 3 ,port 7,8,9 vlan 4 dan port 10,11,12 trunk
setelah itu setting switch dan router dengan CLI seperti di bawah:
Setting Switch tiap lantai bisa lewat config mode atau CLI seperti di bawah

Setting Router
klo ada -> merupakan keterangan syntax ga perlu di aplikasikan di packet tracer .
Router>enable

% Warning: It is recommended to configure VLAN from config mode,
as VLAN database mode is being deprecated. Please consult user
documentation for configuring VTP/VLAN in config mode.

Nah setelah semua setting selesai tes ping ke tiap komputer dalam 1
departemen tapi beda lantai apakah bisa terhubung?klo iya berarti wajar
karena masih dalam 1 vlan. Kemudian ping komputer beda departemen
dalam 1 lantai dan ping lagi komputer yang beda lantai dan beda
departemen. Klo bisa berarti routing sudah berhasil.
