Dynamic Routing OSPF Single Area (in bahasa Indonesia)

OSPF cloud

Dynamic routing adalah routing protocol yang dugunakan antar router untuk mementukan jalur terbaik ke remote network atau network tujuan dan menjaga (maintain) networknya dalam routing table networks. Dynamic routing OSPF adalah routing protocol link state berbeda dengan routing protocol yang distance vector seperti RIP yang dihitung per hop OSPF ditentukan oleh sebuah nilai cost, meski demikian RIP maupun OSPF adalah Routing protocol Open standard. OSPF menggunakan SPF algoritma.

Berikut adalah contoh implementasi OSPF routing di lapangan untuk koneksi broadband mobile. Dalam konfigurasi berikut Core router Singapore sebagai backbone area network dan juga sebagai gateway untuk masing-masing node baik Indonesia atau Australia.
