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. Bagaimana bila router cisco digunakan dengan router lain seperti Juniper, Hwawei, dll menggunakan EIGRP??? Seperti saya bilang diatas, EIGRP hanya bisa digunakan sesama router cisco saja. EIGRP ini sangat cocok digunakan utk midsize dan large company. Karena banyak sekali fasilitas-fasilitas yang diberikan pada protocol ini.
