huawei ağ ekipmanlarında basit ospf uygulaması
ospf detaylarına girmeden huawei ağ ekipmanlarında ospf nasıl kullanabiliriz ve kontrol edebiliriz aşağıdaki örnek topolojide incelemeye çalışalım.
yönlendiriciler üzerine öncelikle arayüz iplerini girelim

R1 üzerinde görüleceği üzere pc1 den pc2 ye ulaşmak istersek R1 üzerinden gerekli yönlendirme yapılamayacaktır. bu yönlendirme işlemini ospf ile yapmaya çalışalım..
R1 üzerine area 0 oluşturalım ve cihaz üzerindeki tüm networkleri ekleyelim
