    Biz load balancing'i manual olarak yapıyoruz . ADSL routerımıza bazı çok
    ziyaret edilen siteleri ekledik .Default route'ı ise ana lease line
    hattımıza verdik . Biz mevcutta 2 ayrı ISP kullanıyoruz . Dolayısı ile
    otomatik load balancing yapamıyoruz . İki ISP kullanarak load balancing
    çözümü cisco da var mıdır ?
    Teşekkürler

    Bu özellik kullanılınca, sanki serial0 mız ve adsl modemimiz de up
    olduğunda, trafik sadece adsl den çıkacakmış gibi gözüküyor, yani load
    balance özelliği kaybolacakmış gibi gözüküyor. Yanılıyor muyum?

    Yalnız bu özellik sadece 1700lerde destekleniyor görülüyor – şimdilik.

    2501 ise bayağı eski bir router hala destek veriliyor mu bilmiyorum.

    Merhaba arkadaþlar,

    Benim elimde 2501 router var. serial 0 ve Ethernet bacaðýna baðlý adsl modem
    load balance çalýþýyor. Sorunum ise: serial 0 down olduðunda direkt bütün
    trafik adsl modem e yönleniyor, ancak adsl modem down olduðunda yine load
    balance yapmaya çalýþýyor.Adsl modem down olduðu halde ona paket göndermeye
    çalýþýyor. Bu yüzden internete olan trafiðimizin yarýsý kaybolmuþ oluyor.bu
    sorunu nasýl aþabiliriz?
