ŞEKİLDEKİ GİBİ AĞ YAPISINI OLUŞTURUYORUZ
OSPF YAPILANDIRMA
1-Trabzon PC1’e 192.168.1.2 ip adresini veriyoruz.
Trabzon Router’ının Fast Ethernet’ine 192.168.1.1 ip adresini veriyoruz.
Trabzon Router’ının Serial 0/0 192.168.6.2 ip adresini veriyoruz.
Trabzon Router’ının Serial 0/1 192.168.7.2 ip adresini veriyoruz.
2- Rize PC1’e 192.168.2.2 ip adresini veriyoruz.
Rize Router’ının Fast Ethernet’ine 192.168.2.1 ip adresini veriyoruz.
Rize Router’ının Serial 0/0 192.168.5.2 ip adresini veriyoruz.
Rize Router’ının Serial 0/1 192.168.6.1 ip adresini veriyoruz.
3- Ankara PC1’e 192.168.3.2 ip adresini veriyoruz.
Ankara Router’ının Fast Ethernet’ine 192.168.3.1 ip adresini veriyoruz.
Ankara Router’ının Serial 0/0 192.168.5.1 ip adresini veriyoruz.
Ankara Router’ının Serial 0/1 192.168.7.1 ip adresini veriyoruz.
Bilgisayar ve Router’lara bu şekilde İP adreslerini verdikten sonra tüm routerlara OSPF’yi aktif hale getirip yapılandırmakta.Bunun için aşağıdaki adımları izliyoruz.

KOMUTLARI GİRİLİR
Bu şekilde Tüm Routerlarda OSPF yapılandırması tamamlanmış olunur.
