    EIGRP Manuel Summarization Konfigürasyonu









    1. R1 Routerında bulunan ve konfigürasyon içerisinde loopback interfaceler ile tanımlanmış networkler S1/1 interface’inden Summarize edilmiştir.
    2. Bu durumda R2 ve R3 routerlarının Routing Table’larındaki fark incelendiğinde Summarization’ın sağladığı avantaj görülebilir.
    3. Auto Summarization özelliği kapatılmıştır.












    Başlangıçta Routerların Routing Table’ları aşağıdaki gibidir..

    R3#
    R1 Routerın’da Manuel Summarization yapuıldıktan sonra R3 routerının Routing Table’ı daha özet hale gelecektir. R1 routeının konfigürasyonu şöyledir:




    Kod:
     R1#sh run
    Building configuration...
    
    Current configuration : 1557 bytes
    !
    version 12.3
    service timestamps debug datetime msec
    service timestamps log datetime msec
    no service password-encryption
    !
    hostname R1

     ip summary-address eigrp 99 172.30.0.0 255.255.0.0 5
    !
    router eigrp 99
     network 12.0.0.0

     network 172.30.0.0
     network 192.168.1.0
     no auto-summary
    !







    Bu durumda R3 Routerının Routing Table’ı şu şekilde değişmiştir;


    Kod:
     R3#sh ip route
    Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
           D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

    C    192.168.3.0/24 is directly connected, FastEthernet0/0
    R3#

    R1 Routerında ise olası bir loop’u önlemek amacıyla 172.30.0.0 networkü için Null0’a bir yönlendirme otomatik olarak eklenmiştir.



    Kod:
     R1#sh ip route
    Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
    
    Gateway of last resort is not set
