Lab 20. OSPF - Point-to-Point (Frame Relay Switching)
Ketika membangun network dengan OSPF maka kita harus menentukan network type apa yang akan digunakan dalam network OSPF kita.
OSPF memiliki beberapa network type yaitu :- Point-to-Point : NO DR/BDR, menggunakan multicast, default hello dan dead interval adalah 10/40.
- Point-to-Multipoint : NO DR/BDR, menggunakan multicast, default hello dan dead interval adalah 30/120.
- Point-to-Multipoint Non Broadcast : NO DR/BDR, menggunakan unicast, default hello dan dead interval adalah 30/120.
- Broadcast : DR/BDR, menggunakan multicast, default hello dan dead interval adalah 10/40.
- Non-Broadcast : DR/BDR, menggunakan unicast, default hello dan dead interval 30/120.
Metode ini paling simple dan banyak digunakan utamanya di ISP, metode point-to-point akan menjadikan network OSPF kita menjadi lebih cepat konvergensinya karna router hanya perlu mempelajari network dari router sebelahnya saja. Pada OSPF point-to-point hello packet akan dikirim dengan multicast dan default hello 10s & dead interval 40s, dalam network Point-to-Point OSPF tidak mengenal DR ataupun BDR karna hanya LSA type 1 (apabila satu area) yang diterima oleh si router.

Test PING
Cek Type Network
Coba cek OSPF Neigbor apakah ada DR/BDR nya ?? :)
Successs..!!!
