EIGRP - 02
Konfigurasi kali ini akan melakukan tehnik men-summarized routing pada routing EIGRP. Summarized routing penting dilakukan, dengan summarized routing maka routing table tetap terjaga ukurannya tidak terlalu besar. Dan berbanding lurus dengan kerja processor yang tidak semakin berat. Pada topologi EIGRP - 02 ini R2 menggunakan 8 loopback interface dengan maksud agar terlihat perbandingan sebelum summarized routing dilakukan dan sesudahnya. Gambar topologi dapat dilihat dibawah,

Setelah konfigurasi awal ini dapat dilihat routing table pada R1 dan R3 yang belum melakukan summarisasi:
Berikut konfigurasi summarized routing di R2 pada kedua interface yang tersambung ke R1 dan R3,
R2(config-router)#exit
R2(config)#int s1/0
R2(config-if)#ip summary-address eigrp 10 10.0.0.0 255.255.248.0

Summarized routing telah berhasil dilakukan. Berikut routing table pada R1 dan R3, dan bandingkan dengan routing table sebelum melakukan summarized routing diatas.
