  3. Why Routing is Important ???

  4. ROUTING = PERJALANAN PERGI & PULANG HARUS DIKONFIGURASI DI ROUTER PENGIRIM & PENERIMA

  5. R1 R2 192.168.1.0/24 10.10.1.0/24 INTERNETWORK CONNECTION ROUTER DAPAT MENGHUBUNGKAN 2 JENIS ATAU LEBIH ALAMAT JARINGAN YANG BERBEDA

  6. BEST PATH Untukmencapaitujuan Router dapatmelakukan pengambilankeputusandalammenentukanruteterbaik Ruteterbaik= Jalanterpendek/Bandwidth lebar/Delay rendahdsb

  7. Jenis Routing Statis Dinamis

  8. Jenis Routing Statis= Simple, Praktis, no ribet • Hanyacocokuntukjaringankecil/sederhana • Diperlukan input secara manual disetiap router saatpenambahanjaringanbaru • Tidakcocokuntukjaringankompleksdenganbanyak router

  9. Jenis Routing Dinamis= Powerfull, kompleks • Cocokuntukjaringanbesardenganbanyak router • Skala enterprise / ISP • Diperlukan skill / pengetahuanrouting yang baik • Dapatmenanganijaringankompleks multi vendor, multi ISP maupunantar Negara • Biayatinggikarenamembutuhkanspesifikasi router khusus

  10. ROUTING STATIS

  11. ROUTING FORMULA IP ROUTE (JARINGAN YG DITUJU) (SUBNET MASK)(IP ROUTER TETANGGA/OUT INTERFACE ROUTER PENGIRIM)

  12. Router Interface (PORT) ROUTER MEMPUNYAI 2 INTERFACE ATAU LEBIH -> KE JARINGAN INTERNAL (SBG GATEWAY & MENUJU MODEM INTERNET ATAU ROUTER LAINNYA INTERFACE SERIAL DIGUNAKAN UNTUK KONEKSI JARINGAN WAN
