LAB 1 OSPF Virtual Link
Skenario : Menjalankan OSPF pada kondisi dimana ada area yang tidak terhubung dengan Area 0 , dalam hal ini dengan menggunakan Virtual Link.
Note : pada OSPF agar bisa ikut dalam berpartisipasi dalam network OSPF syaratanya adalah setiap AREA harus terhubung ke Area 0.
Jika tidak terhubung Area 0 , maka bisa memakai Virtual Link dan GRE TUNNEL untuk bias terhubung ke AREA 0
Pada metode Virtual Link, tidak dibutuhkan alokasi IP tambahan.

Skenario : Lab NSSA untuk bias melewatkan Eksternal route yang tidak bias dilakukan pada dua model stub sebelumnya.
Note :
- NSSA bias melewatkan eksternal dan internal route area yang berbeda. Untuk Eksternal route ( LSA5) pada NSSA diubah menjadi LSA 7.
- NSSA harus dikonfigurasi pada semua router stub pada area yang sama.
- default-information-originate no-summary untuk menginject default gateway
- no summary dibelakang default-information-originate berarti : tidak menampilkan internal route area lain pada database.
