More than just Technology

EIGRP (Enhanced Interior Gateway Routing Protocol) adalah routing protocol yang hanya di adopsi oleh router cisco atau sering disebut sebagai proprietary protocol pada cisco. Dimana EIGRP ini hanya bisa digunakan sesama router cisco saja. EIGRP ini sangat cocok digunakan utk midsize dan large company. Karena banyak sekali fasilitas2 yang diberikan pada protocol ini.

Hal-hal dasar yang perlu diketahui
EIGRP sering disebut juga hybrid-distance-vector routing protocol, karena EIGRP ini terdapat dua tipe routing protocol yang digunakan, yaitu:
- distance vector, dan
- link state.
Utk tipe2 routing protocol akan saya tambahkan sehabis penjelasan tentang EIGRP.
EIGRP ini pengembangan dari routing protocol IGRP (distance vector), prorpietary cisco juga. Perbandingan (bukan perbedaan) antar IGRP dan EIGRP di bagi menjadi beberapa kategori:
1. Compability mode
2. Metric colocation
3. Hop count
4. Automatic protocol redistribution
5. Route tagging

EIGRP mempunyai 3 table dalam menyimpan informasi networknya:
1. Neighbor table
2. Topology table
3. Routing table

Penjelasan :

Berikut contoh topology menggunakan EIGRP :
