Tipe LSA dan Kode Routing Table OSPF
Berikut adalah type route OSPF yang biasa muncul di output dari perintah “show ip route”:
| Tipe LSA |
Kode |
Deskripsi |
| 1 (Router) | O | Digenerate oleh semua router; daftar neighbor dan cost menuju mereka; dipropagasi di dalam satu area |
| 2 (Network) | O | Digenerate oleh DR pada multiaccess network; dipropagasi di dalam satu area |
| 3 (Inter-area summary) | O IA | Mengadvertise summary dari satu area ke area lainnya |
| 4 (ASBR Summary) | O IA | Mengadvertise lokasi dimana ASBR berada |
| 5 (External) | O E1/O E2 | Mengadvertises ruter eksternal ke dalam Autonomous System |
