EIGRP adalah
protocol routing buatan cisco, jadi kita tida mungkin bisa menggunakan protocol
routing ini pada perangkat lain selain cisco, seperti mikrotik, juniper, ataupun
perangkat lainnya.
EIGRP
menggunakan perhitungan yang disebut sophisticated metric. Ada formula
matematikan yang menggunakan pola perhitungan. Sedangkan variable yang
mempengaruhi perhitungan antara lain :
1.Bandwith didefinisikan sebagai 107 kbps dibagi dengan link terlambat (slowest link) diantara link atau
path yang ada. Dengan demikian, path terbaik atau route terbaik akan memilih nilai atau cost paling kecil
(lower cost).
2.Load dan Reliability adalah nilai sebesar 8 bit, yang dihitung berdasarkan performa terbaik. Biasanya
nilai load dan relability berbilai 0.
3.Delay bernilai konstan untuk setiap jenis interface. Delay diukur dalam satuan mikrodetik. Sebagai contoh,
3.Delay bernilai konstan untuk setiap jenis interface. Delay diukur dalam satuan mikrodetik. Sebagai contoh,
serial link memiliki delay 20.0000 mikrodetik dan delay Ethernet 1000 mikrodetik.
4.Dual Sebagai protocol routing menggunakan algotritma Bellman-Ford. Sedangkan EIGRP menggunakan
diffusing update algoritma (DUAL). Proses kalkulasi terbesar (diffuse) diantara router-router.
Tahap-tahap yang dilakukan adalah :
1.Konfigurasi IP Address untuk masing-masing interface pada R1, seperti berikut.
Router>enable
Router#configure terminal
R1(config)#interface fastEthernet 0/0
R1(config-if)#ip address 192.168.1.1 255.255.255.0
R1(config-if)#no shutdown
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
R1(config-if)#interface serial 0/3/0
R1(config-if)#ip address 12.12.12.1 255.255.255.0
R1(config-if)#no shutdown
%LINK-5-CHANGED: Interface Serial0/3/0, changed state to down
R1(config-if)#exit
R1(config)#do wr
