Nyoman Suryadipta, ST, CCNP
Routing = RutePengirim ke PenerimaRouting = Router
Why Routing is Important ???
ROUTING = PERJALANAN PERGI & PULANG HARUS DIKONFIGURASI DI ROUTER PENGIRIM & PENERIMA

INTERNETWORK CONNECTION ROUTER DAPAT MENGHUBUNGKAN 2 JENIS ATAU LEBIH ALAMAT JARINGAN YANG BERBEDA
BEST PATHUntuk mencapai tujuan Router dapat melakukan
pengambilan keputusan dalam menentukan rute terbaik
Rute terbaik = Jalan terpendek/Bandwidth lebar/Delay rendah dsb
Jenis Routing
Statis Dinamis
Jenis Routing
Statis = Simple, Praktis, no ribet •Hanya cocok untuk jaringankecil/sederhana•Diperlukan input secara manual disetiap router saat
penambahan jaringan baru •Tidak cocok untuk jaringan kompleks dengan banyak
router
Jenis Routing Dinamis = Powerfull, kompleks • Cocok untuk jaringan besar dengan banyak router• Skala enterprise / ISP • Diperlukan skill / pengetahuan routing yang baik• Dapat menangani jaringan kompleks multi vendor, multi ISP
maupun antar Negara • Biaya tinggi karena membutuhkan spesifikasi router khusus
ROUTING STATIS
ROUTING FORMULA
IP ROUTE (JARINGAN YG DITUJU) (SUBNET MASK) (IP ROUTER TETANGGA/OUT INTERFACE ROUTER PENGIRIM)
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

GROUP PRACTICE
Routing Statis tidak bisa menangani Routing dengan Banyak jalur alternatif (multipath routing)
Routing Dinamis dapat menangani Multipath RoutingDan mencari Rute alternative jika jalur Utama terputus
IGP = Interior Gateway Protocol EGP = Exterior Gateway Protocol
