Hmm..<\/p>\n

Artikel kali ini kita akan membahas routing protokol dinamis lainnya, yaitu EIGRP. Routing protokol ini adalah Cisco Proprietary<\/em> yang artinya hanya dapat dijalankan di perangkat Cisco saja. Hanya sedikit dokumentasi yang ditemukan menjadikan routing protokol ini tidak terlalu \u201cterbuka\u201d rahasia dan kemampuannya.<\/p>\n

Perhitungan metrik secara advance pada EIGRP untuk menentukan jalur terbaik berdasarkan nilai bandwidth, delay dan reliability. Agak lumayan ribet juga rumusnya. Buat yang mau hitung-menghitung rumusnya silahkan merujuk ke Wikipedia<\/strong>. EIGRP secara dasar juga merupakan jenis Distance Vector Routing Protocol <\/em>sama seperti RIP yang juga menggunakan hop count sebagai metrik.<\/p>\n

Langsung menuju hands on..<\/p>\n

Kita masih menggunakan topologi yang sama dan hanya perlu \u201cmenimpa\u201d konfigurasi routing protokol bekas yang lama (OSPF). By default<\/em>, sebuah router cenderung memilih routing protokol dengan AD (Administrative Distance<\/em>) yang lebih kecil jadi meskipun di dalam sebuah router terdapat beberapa routing protokol yang diterapkan, ia hanya memilih routing protokol dengan AD yang paling kecil.<\/p>\n

\"ScreenShot328\"<\/a><\/p>\n

Berikut konfigurasi EIGRP pada router Semarang.<\/p>\n

SMG#conf t
Enter configuration commands, one per line.  End with CNTL\/Z.
<\/em>SMG(config)#router eigrp 13<\/strong>
SMG(config-router)#net 192.168.40.2
SMG(config-router)#net 192.168.40.2
SMG(config-router)#net 192.168.50.1
SMG(config-router)#net 5.5.5.5
SMG(config-router)#net 128.5.5.5
SMG(config-router)#net 192.5.5.5
SMG(config-router)#no auto-summary<\/strong>
SMG(config-router)#end<\/p>\n

Perhatikan perintah yang dicetak tebal.<\/p>\n

SMG(config)#router eigrp 13 \u2013> <\/strong>melakukan konfigurasi routing protokol EIGRP dengan Autonomous system number 13. Nilai ini harus sama pada semua router yang ingin dihubungkan.<\/p>\n

SMG(config-router)#no auto-summary \u2013> <\/strong>memberikan perintah supaya EIGRP mendukung VLSM.<\/p>\n

Lakukan konfigurasi serupa pada seluruh router sehingga hasil akhirnya full reachability pada tiap loopback interface.<\/p>\n

Berikut hasil show ip route<\/strong> pada router ISP.<\/p>\n
