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..
Kod:
R1#sh ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

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
!

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
