OSPF
Ada tiga (3) elemen dasar konfigurasi OSPF:
- Enable OSPF instance
- OSPF area configuration
- OSPF network configuration
instance name=default sudah ada, tidak perlu di tambahkan, tapi kalau perlu menambahkan caranya adalah sebagai berikut Catatan: Ingat bahwa backbone area-id adalah 0.0.0.0.
