Jaringan Informasi: IMPLEMENTASI

Desain Sistem

Tahap model konseptual sistem terdiri dari desain topologi, konfigurasi area routing OSPF dan pengujian. Untuk implementasinya digunakan software Packet tracer Versi 5.2 . Packet tracer merupakan sebuah software yang digunakan untuk melakukan simulasi jaringan. Software ini dikembangakan oleh sebuah perusahaan yang bergerak dalam masalah jaringan yaitu Cisco.

Tahap-tahap proses implementasi digambarkan sebagai berikut:

1.1.Desain Topologi dan Konfigurasi Jaringan

Untuk menentukan model Jaringan OSPF yang optimal, maka dilakukan desain topologi dan area jaringan, serta konfigurasi routing OSPF yang berbeda-beda. Percobaan ini dilakukan dengan 8 buah router dan 1 buah PC yang masing-masing terhubung dengan router. Dengan OSPF, maka jaringan akan dibagi menjadi tingkatan yang dinamakan sistem pengelompokan area. Berikut konfigurasi masing-masing PC:

Tabel 1. Konfigurasi PC

Nama PC	IP	Gateway	Router
PC 1	192.168.10.2	192.168.10.1	Router 1
PC 2	192.168.20.2	192.168.20.1	Router 2
PC 3	192.168.30.2	192.168.30.1	Router 3
PC 4	192.168.40.2	192.168.40.1	Router 4

PC 6	192.168.60.2	192.168.60.1	Router 6
PC 7	192.168.70.2	192.168.70.1	Router 7
PC 8	192.168.80.2	192.168.80.1	Router 8
