    1) Router A'da RouterB nin ethernet bacagi icin static address olmasi
    gerekli..

    yani router A> ip route RouterB_ethernet_address 255.255.255.X
    xx.xx.244.58

    yada routerlar arasinda EIGRP kullan, o zaman static koymana gerek
    kalmaz..

    2) eger bu Internet de olacak ise zaten private adres kullanamazsin,cunku
    ISP routerlerin cogu private adresleri bloklar...

    3) Serial connection icin IP address kullanmasan da olur ;veya Ethernet
    adresini kullanabilirsin.

    iyi gunler Arkadaslar,

    Switche bagli 1 routerimizin (Router A: ethernet i XXX.XXX.247.2/25 serial
    0 ip`si XXX.XXX.244.57/30) seri portuna (serial 0) bir kucuk access server
    (Router B ip`si XXX.XXX.244.58/30) bagliyoruz 4 portlu.

    Ana Cisco router <--> switch <--->eth0 Cisco Router A ser 0 <---->
    Cisco Router B

    router B'deki trafigi switch'e tasimak icin ugrasiyoruz. /30 daki block
    Router A'ya ulasiyor, ana router tarafindan routing XXX.XXX.244.32/27
    Router A a yonlenirilmistir, traceroute ile gorebiliyoruz. Ama sorunumuz
    Router A ser0'a ve Router B'ye ping atamiyoruz, Router A'daki serial port
    herseyiyle up gorunmektedir. Herhangi bir fikriniz var mi?

    Ayrica bu /30 yerine private IP kullanmak guvenlik acisindan
    ne kadar saglikli olur? Sonucta bu makinalar internet servisi veren bir
    network uzerinde olacak.

    Ana routerde
    ip route xxx.xxx.244.32 255.255.255.224 eth0_IP_router_A

    Saygilar,
    -Mehmet
