TCP/IP: Quagga Apakah Itu?
Quagga adalah software routing open source berbasis pada router Zebra, yang proses pengembangannya telah berhenti di tahun 2003. Quagga mendukung protokol routing standard seperti RIP, OSPF atau BGP dan dapat di instalasi di semua sistem Linux dengan kernel 2.4 atau yang lebih tinggi.
Quagga terdiri atas beberapa daemon, satu daemon per protokol routing dan sebuah daemon bernama Zebra yang berfungsi sebagai kernel routing manajer. Setiap daemon mempunyai file konfigurasi sendiri dan interface terminal yang dapat di akses menggunakan telnet.
Tool vtysh di sediakan untuk mengkonfigurasi router Quagga melalui localhost, dengan interface yang unik.
Quagga works independently from the operational system (OS) over which it is installed. This is not the case for the open source Vyatta router or the commercial routers where the OS and the routing engine are built together. With Vyatta routers, you can access the operational system (a modified version of the Debian Linux distribution) but even this is not necessary to configure the router.
With commercial routers like Cisco or Nortel, you can access only the router interface.
It must be emphasised that Quagga owns only routing capabililies and functionalities associated with it, such as access lists or route maps. It does not provide "non-routing" functionalities such as DHCP server, NTP server/client or ssh access but it is often possible to enable them on the operating system supporting your Quagga router. See the Routers' comparison to get an overview about the functionalities available with Cisco, Vyatty or Quagga routers.
Interface Command Line Quagga sangat mirip dengan Cisco IOS sehingga sangat mudah untuk mengkonfigurasi-nya bagi mereka yang familiar dengam Cisco.
