Step 8: Verify connectivity

REFLECTION:

a. what is the advantage of using VTP to manage VLANs
b. what are some advantages and disadvantages of implementating VLANs
c. what required for host on different VLANs to communicate with each other?

a.we can create, modify, and delete VLAN parameters
   VLAN configuration to the entire domain by using a single switch
   which switches that use the server mode

b.advantages:
1. Reduce network traffic (traffic load), because the VLAN segmentation done
  LAN into several smaller LANs.
2. Optimization of network more flexible, because the grouping is not based on user
  physical location, but can be done based on the similarity field / job / division / department.
3. The security level is guaranteed, because it separates the users who work using data
  sensitive at a logically separate VLAN.
4. Save costs, because the distribution layer network into several groups of broadcast domains
  smaller, thus reducing the amount of purchases that much more expensive routers.
5. Ease of network management, by dividing the number of administrators for each subnet.

  loss:
1.loss defines VLANs based on port is a manager network must merekonfigurasi membership
VLAN when one user moves from one port to another p o r t
2.loss of VLANs based on MAC addresses are all user must be configured to be
VLAN members. After manual configuration , the search is an automatic user possible, depending on the product switches are used where a specific vendor.

c.required by the host to communicate on a different vlan is a router


a. apa keuntungan dari menggunakan VTP untuk mengelola VLAN
b. sebutkan beberapa keuntungan dan kerugian dari implementasi VLAN
c. apa yang diperlukan untuk host pada VLAN yang berbeda untuk berkomunikasi satu sama lain?

a.kita dapat membuat, mengubah, menghapus VLAN dan parameter
  konfigurasi VLAN ke seluruh domain dengan menggunakan satu switch
  yaitu switch yang menggunakan mode server

b.keuntungan:
1.Mengurangi traffik jaringan (load traffic), karena dalam VLAN dilakukan segmentasi
 LAN menjadi beberapa LAN yang lebih kecil.
2.Optimasi jaringan yang lebih flexible, karena pengelompokan user tidak berdasarkan
 lokasi fisik, tapi bisa dilakukan berdasarkan kesamaan bidang/pekerjaan/divisi/departemen.
3.Tingkat keamaan lebih terjamin, karena memisahkan user-user yang bekerja menggunakan data-data
 yang sensitif pada satu VLAN yang terpisah secara logika.
4.Menghemat biaya, karena pembagian jaringan layer ke dalam beberapa kelompok broadcast domain
 yang lebih kecil, sehingga mengurangi jumlah pembelian router yang jauh lebih mahal.
5.Memudahkan manajemen jaringan, dengan membagi beberapa administrator untuk tiap subnet.

   kerugian:
1.kerugian mendefinisikan VLAN berdasarkan port adalah manajerjaringan harus merekonfigurasi keanggotaan
VLAN ketika salah satu user berpindah dari satu port ke p o r t lainnya
2.kerugian dari VLAN yang berdasarkan alamat MAC adalah semua user harus dikonfigurasi untuk menjadi
anggota VLAN. Setelah konfigurasi manual tersebut, pencari an otomatis user sangat
dimungkinkan, tergantung pada produk switch vendor mana yang digunakan tertentu.

c.yang dibutuhkan oleh host untuk berkomunikasi pada vlan yang berbeda adalah router
