Cisco : Dynamic Routing - EIGRP

EIGRP adalah singkatan dari Enhanced Interior Gateway Routing Protocol. Ini adalah protokol routing yang dikembangkan oleh Cisco Systems dan digunakan dalam jaringan komputer untuk mengambil keputusan routing dan menyebarkan informasi routing. EIGRP merupakan versi yang ditingkatkan dari Interior Gateway Routing Protocol (IGRP) dan memadukan fitur dari protokol routing vektor jarak dan protokol routing link-state.

EIGRP umum digunakan dalam jaringan perusahaan berukuran menengah hingga besar, terutama yang menggunakan peralatan jaringan Cisco. Namun, penting untuk dicatat bahwa sebagai protokol yang dimiliki secara proporsional oleh Cisco, EIGRP utamanya digunakan dalam lingkungan Cisco dan mungkin tidak dapat berinteroperabilitas dengan perangkat non-Cisco.

Syntax

EIGRP Configuration

Command Description
R1(config)#router eigrp [AS-number] [AS-number] value = 1-65535.
R1(config-router)#eigrp router-id [a.b.c.d] (optional) manual konfigurasi router-id
R1(config-router)#network [network-address] classfull network
R1(config-router)#network [network-address] ([wildcard-mask])recomend: classless network
  • Apabila router ID tidak dikonfigurasi, router akan memakai Ipv4 dari loopback interface tertinggi dari interface yang aktif. Apabila tidak ada loopback interfaces maka router ID akan memakai Ipv4 dari physical interface tertinggi

EIGRP Verification

Command Description
R1#show ip protocols
R1#show ip eigrp neighborsMenampilkan EIGRP neighbors
R1#show ip route eigrp eigrp only route tables
R1#show ip eigrp interface
