    Zafer,

    Serial 3/0 uzerinde fast-switching yaptigin icin paketler o hatti
    kullaniyor. Serial 3/0 uzerinde 'no ip route-cache' bir cozum olur ama
    oldukca kotu bir cozum olur, router tum paketleri process switch eder ve
    performans hayli duser.

    CEF calistirarak (ip cef ve ip route-cache cef) ya da iki hatti
    Multilink PPP ile bir bundle olarak kullanarak bu sorunu cozebilirsiniz.
