DYNAMIC ROUTING EIGRP - Cisco - CCNA - Packet Tracer ~ CATATANKU

Posting kemaren kita bahas juga dynamic routing tapi menggunakan RIP V2, untuk kesempatan kali ini kita bahas dynamic routing menggunakan EIGRP yang dulunya adalah Proprietary (khusus) dari CISCO, konsep dasar dari EIGRP ialah sebuah routing protocol yang menggunakan distance vector atau juga di sebut advanced distance vector atau routing protocol hybrid, EIGRP juga menggunakan ASN(autonomous system number) yang berguna untuk sharing infomasi antar router, dengan ASN yang sama Router akan bisa saling menukar informasi.

#. EiGRP memilik banyak fitur di antaranya:

· Cisco open standard Protocol (sebelumnya Proprietary)

· Classless routing Protocol

· Update perubahan Topology secara dinamis

· Metric (32 bit): Compatible Metric (bandwidth + Delay + Load + MTU + Reliability)

· Administrative Distance: 90

· Update menggunakan Multicast: 224.0.0.10

· Jumlah Max. HopCount: 255 (default 100)

· Mendukung Protocol: IP, IPX, Apple Talk

· Hello Packet di kirim setiap 5 second (Dead Interval 15 second)

· Konvergensi cepat (waktu yang di butuhkan oleh router untuk menggunakan route alternative pada saat best route down).

· Menggunakan Algoritma Dual (Diffusing Update Algoritma)

· Mendukung Equal dan enequal cost Load Balancing.

#. Autonomous System Number (ASN)

· nomor unik mengidentifikasi domain routing dari router.

· Autonomous System adalah kumpulan dari jaringan di bawah domain administrasi umum.

- Ranges dari 1 – 65535, terbagi antara:

- Public AS (diantara beberapa SP) : 1 – 64512

- Private AS (sama SP) : 64513 - 65535

#. Klassifikasi Routing Protocol

#. EIGRP Metrics

· EIGRP menggunakan perhitungan Bandwith + Delay + Load + MTU + Realliability

· Secara Default perhitungan metricnya Bandwith dan Delay

· Perhitungan menggunakan Rumus default K values (K1= 1, K2= 0, K3= 1, K4= 0, K5= 0): Metric = [K1 * BW + ((K2 * BW)/(256-load)) + K3 * Delay]

#. Ada dua Step untuk konfigurasi Dynamic Rouitng di Cisco

1. Pilih routing protocol

2. Advertise Network pada interface Directhly Connected (mengenalkan jaringan yang terhubung langsung di router kepada router lainnya).

#. Konfigurasi EIGRP Cisco

Router (config)#router eigrp <AS Nomer>

Router (config-router)#network <Network-ID>

Router (config-router)#network <Network-ID> <Wildcard-Mask>

Router (config-router)#no auto-summary

Router (config-router)#exit

Ketrangan:

- <AS NOMER>: nomer autonomous system 1-65535

- <Network-ID>: mengadvertise network yang terhubung langsung yang berada di router (directhly connected network).

- <wildcard-mask>: membalikkan bit/binner pada subnet mas normal.

· untuk menyatakan Match sebuah Host bisa menggunakan 2 cara:

- dengan WILDCARD Mask “0.0.0.0”, misal 192.168.1.1 0.0.0.0

- dengan Keyword “host”, misal host 192.168.1.1

· untuk menyatakan Match semua host bisa menggunakan 2 cara:

- dengan WILDCARD Mask “255.255.255.255”, misal 0.0.0.0 255.255.255.255

- dengan Keyword “any”, misal any <IP source> atau <IP destination>

#. EIGRP Cek konfigurasi atau buat Troubleshoting

1. Neighbor table

· Menampilkan informasi tetangga atau directly connected

· Command: show ip eigrp neighbor

2. Topology table

· Menampilkan best route yang ada di routing table dari masing – masing neighbor.

· Command: show ip eigrp topology

3. Routing Table

· Menampilkan best rout menuju network destination

· Command: show ip route

#. LAB EIGRP Pada Packet Tracer

- Topology:

- Keterangan:

- N= Network

- Gi0/0= nama port interface

- IDN..= nama router

#. Konfigurasi tiap – tiap Router sesuai topology di atas:

- R1:

Router>enable

Router#conf t

Enter configuration commands, one per line. End with CNTL/Z.

idn1(config)#hostname idn1

idn1(config)#int gi0/0

#. REVIEW

- Keunggulan EIGRP:

· Terdapat backup route apabila best route down (successor= Primary, feasible successor= backup)

· Mendukung VLSM

Sampai di sini dulu yoo untuk Pembahasan mengenai EIGRP dan komplotannya, mohon maaf apabila ada kesalahan dalam penulisan maupun kata – kata yang kurang berkenan, semoga bisa bermanfaat bagi kita semua terimakasih.
