    Teşekkurler.
    Serial 3/0'in altindaki no ip mroute-cache beni yaniltmis. Fast switching'i
    disable ettigimde yuk dagilimi esitlendi. Cef aktif edersem yine yuk
    dagilimi esit olmayacaktir diye dusunuyorum. Bildigim kadariyla cef
    destination'a gore switching yapiyor. Multilink'i deneyecegim.
    Tesekkurler...

    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.

    Ilker
