Ada tiga (3) elemen dasar konfigurasi OSPF:
- Enable OSPF instance
- OSPF area configuration
- OSPF network configuration
Catatan: Ingat bahwa backbone area-id adalah 0.0.0.0.
R1
enable configure terminal ! ! area 0 = backbone router ospf 1 network 10.10.1.0/30 area 0.0.0.0 network 10.10.1.4/30 area 0.0.0.0 area 0.0.0.0 authentication message-digest end
R2
enable configure terminal ! ! area 0 = backbone router ospf 2 network 10.10.1.4/30 area 0.0.0.0 network 10.10.1.8/30 area 0.0.0.0 network 172.16.0.0/16 area 0.0.0.0 area 0.0.0.0 authentication message-digest end
R3
