====== Cisco Labs : Studi Kasus Desain Jaringan  (BNSP)======
PT. Jaya Net Persada memiliki 4 bagian, yaitu:
  * Bagian **Pemasaran**
  * Bagian **SDM**
  * Bagian **Teknik**
  * Bagian **Keuangan**

Direktur perusahaan ingin mengembangkan infrastruktur IT di perusahaannya. Perusahaan tersebut berkantor di sebuah gedung 4 lantai. Setiap bagian harus memiliki jaringan yang terpisah, namun tetap saling terkoneksi (dapat berkomunikasi).

Setiap bagian memiliki:
  * 1 server
  * 1 wireless access point
  * Maksimal 60 client (termasuk WiFi)

Seluruh jaringan terhubung menggunakan Fast Ethernet dengan kabel UTP Cat.5e.

===== Pertanyaan =====

Anda sebagai Network Administrator diminta untuk mewujudkan kebutuhan tersebut. Direktur menyediakan perangkat berikut:

  - 1 buah Router Cisco 2811
  - 4 buah Switch Cisco 2960
  - 4 buah Wireless Access Point 802.11b (generic)
  - 4 buah Server
  - Kabel UTP Cat.5e (4 box)
  - 1 blok IP address 192.168.1.0/24
  - 8 buah PC
  - 4 buah Laptop (Wireless)

**Tugas:**
  * Buatlah desain jaringan tersebut
  * Jelaskan desain jaringan
  * Tuliskan alokasi IP address

===== Alokasi Subnet =====

^ Subnet ^ Network Address ^ First Host ^ Last Host ^ Broadcast ^
| Pemasaran (L1) | 192.168.1.0/26   | 192.168.1.1   | 192.168.1.62  | 192.168.1.63  |
| SDM (L2)       | 192.168.1.64/26  | 192.168.1.65  | 192.168.1.126 | 192.168.1.127 |
| Teknik (L3)    | 192.168.1.128/26 | 192.168.1.129 | 192.168.1.190 | 192.168.1.191 |
| Keuangan (L4)  | 192.168.1.192/26 | 192.168.1.193 | 192.168.1.254 | 192.168.1.255 |

Subnet mask: /26 = 255.255.255.192

Keterangan:
  * IP usable pertama → Gateway
  * IP usable kedua → Server (static)
