Terminology yang mesti harus dikenali
Terminology yang mesti harus dikenali
- hop count : skala ukur jarak dihitung dari beberapa router yang dibutuhkan untuk mencapai tujuan
- metric : ukuran biaya sebuah rute untuk mencapai tujuan
- setiap routing protocol menggunakan metric yang berbeda
* RIP menggunakan hop count ( loncatan router)
* OSPF menggunakan bandwidth
* EIGRP menggunkan bandwidth , Delay , Load , Reliability .
-Administrative Distance : tingkat kepercayaan router untuk routing protocol .
* setiap vendor memiliki nilai AD yang berbeda untuk setiap routing protocol
* Pada router cisco , nilai AD secara default :
* RIP 120
* OSPF 110
* EIGRP 90
* Static 1
* Directly Connected 0
* Unknown 255
-convergence : suatu keadaan jaringan dimana setiap jaringan dapat menjangkau seluruh jaringan yang ada ( routing table memiliki informasi yang lengkap )
-convergence Time : waktu yang diperlukan untuk mencapai convergence
* Slower convergence : RIP . IGRP
* Faster Convergence : OSPF , EIGRP
Pemilihan Route yangh masuk ke routing table adalah route yang memiliki AD terkecil , serta diantara AD yang sama , dipilih metric yang terkecil .
Dynamic RP umumnya memiliki 2 operasi yaitu network discovery dan routing table maintenance
IGP Dynamic Routing Protocol dibagi menjadi 2 yaitu :
Distance Vector :
-mengenai jarak ( hop -count ) dan arah saja
-sangat tergantung tetangga
-umumnya mencapai convergence dengan cara mengirimkan complete rouitng table secara estafet
-mengenal adadnya periodic update
-umumnya menggunakan algoritman bellman-ford
