Konsep Dasar

Static default route adalah static route dengan network address destination 0.0.0.0 dan subnet mask 0.0.0.0. Dikenal juga sebagai “quad zero” route. Static default route melakukan identifikasi gateway yang akan digunakan oleh router untuk mengirimkan semua paket IP untuk network destination yang tidak diketahui di routing table, sehingga akan diforward ke route 0.0.0.0/0.

Untuk konfigurasi static default route dapat menggunakan next-hop ip address atau exit-interface.

Router(config)# ip route 0.0.0.0 0.0.0.0 {ip-address or exit-intf}
Static default route:
 Default route dapat digunakan ketika network destination tidak diketahui (Internet)
 Default route dapat digunakan ketika hanya ada satu jalur keluar untuk semua network
destination
 Dapat mengurangi ukuran routing table
 Jika router tidak menemukan entry network destination di routing table, maka router akan
memforward paket ke default route
 Menjadi route pilihan terakhir di routing table
