CONFIGURATION ROUTING EIGRP

Configurasi dasar EIGRP

Routing dynamic EIGRP (enhanched interior gateway protocol)

EIGRP adalah protocol routing buatan cisco, jadi kita tidak mungkin bisa menggunakan protocol routing ini selain cisco, juiniper, ataupun perangkat lainnya

EIGRP menggunakan perhitungan yang disebut sophisticatd metric, ada formula matematika yang digunakan dalam perhitungan, sedangkan variable yang mempengaruhi perhitungan antara lain.

1.      Bandwith
bandwith didefinisikan sebagai 107 kbps dibagi dengan link terlambat (slowest link) diantara link atau pat yang ada, dengan demikian path terbaik rute terbaik akan memiliki nilai atau cost paling kecil (lower cost)

2.      Load dan reliability
load dan reliability adalah nilai sebesar 8 bit, yang dihitung berdasarkan performa terbaik biasanya nilai load dan reliability bernilai 0

3.      Delay
Delay adalah bernilai konstan untuk setiap interfaces, delay diukur dalam satuan microdetik, sebagai contoh, serial link memiliki, 20.000 microdetik  dan delay enthernet bernialim 100 microdetik

Dual
sebagai protocol routing menggunakan algoritma bellma-ford. Sedangkan EIGRP menggunakan diffusing update algoritma(DUAL). Proseses kalkulasi sebesar(diffuse) diantara router – router

Config R1

Matikan terlebih dahulu dengan mengklik ikon power pada router lalu  Ganti port cable dengan

pilih WIC - 1T

Lalu coba dengan masuk cmd PC jika berhasil akan muncul seperti dibawah ini

jika muncul seperti diatas maka berhasil
