Konfigurasi OSPF

Konfigurasi OSPF

Melanjutkan postingan sebelumnya, klu pada postingan sebelumnya kita telah membahas konsep dasar protokol routing OSPF pada jaringan disini, sekarang akan kita bahas mengenai konfigurasinya dengan studi kasus ssederhana tiga router dengan topologi seperti pada gambar dibawah

LANGKAH KERJA

Pada seluruh Router, lakukan Remove Configuration terlebih dahulu:

Pengaturan di Router Utama

1. Pertama, ada baiknya kita merubah nama interface yang akan digunakan supaya lebih jelas. Caranya klik pada Tab Interface, kemudian Ubah namanya sesuai kebutuhan.
