Kali ini kita akan melakukan konfigurasi OSPF.
Buat yang lupa-lupa ingat atau belum pernah ingat sama sekali tentang OSPF saya akan mencoba untuk menjelaskannya secara ringkas.
OSPF (Open Shortest Path First) merupakan salah satu jenis routing protocol.
OSPF termasuk ke dalam routinOSPF akan memilih jalur berdasarkan bandwith.
Namun kali ini kita akan melakukan konfigurasi OSPF basic (multi area).
