    Lightbulb OSPF Routing, EIGRP Redistribute

    Merhaba,

    Aşağıdaki gibi basit bir topoloji oluşturdum 3 Router arasında OSPF 1 Router'da Eigrp çalıştırıyorum.

    Eigrp'yi redistribute ediyorum (yada ettiğimi zannediyorum) fakat Eigrp tarafındaki networklere ulaşamıyorum. Eigrp kendi içerisinde aktif durumda. Burda eigrp ye erişemememdeki problem neden olabilir ? Bunun haricinde Aşağıda R2 Neighbor olarak R0 ı görmekte burda direct connect olarak R1 i görmesi gerekmezmi ?

    Routerların sh run, route ve neighbor çıktıları aşağıdaki gibidir.

    R0 Confg.

    Selamlar,

    oncelikle router 1'in serial 1/1 interface'deki subnetini duzeltmeniz gerekiyor. 255.255.255.0 yapmissiniz bunu 255.255.255.252 yapmalisiniz.

    onun disinda bir sorun goremedim acaba virtual link tanimlamak mi gerekecek? hmm..

    Selam,

    Bu şekilde bir değişiklik yaptım fakat durum aynı şekilde, gözüken bir problem varmıdır ?

    traceroute verebilir misin bu arada bana router 0'dan diğer networklere?

    bir de o şekilde sonuçlara bakalım..

    bu arada tam conf versen bu durumlarda daha iyi olur.. hani default gateway tanımı var mı yok mu gibi..
