Vyatta small ISP Border router

Vyatta винаги ми е била слабост, признавам си. А и идеята да събереш различните инструменти в един функционален шел е повече от добра. Навсякъде където може да се вземе мрежово решение с Линукс мисля първо за нея. И не защото съм предал другите дистрибуции а защото найстина се убедих в нейната функционалност и лекота на работа. Като се замисли човек първо получаваш един добре оптимизиран рутер с шел ала Juniper а после можеш да ползваш всяко хранилище на Debian и да си инсталираш каквото пожелаеш от света на Линукс. Също мисля, че на много места я подценяват но ако проекта върви така за бъдеще може да се превърне и в нещо като стандарт при Линукс рутерите. В долната конфигурация имах нужда от граничен маршрутизатор който замених от Debian към Vyatta и въпреки, че самата vyatta е дериват на Debian се държа доста различно главно поради различния подход към конфигуриране на мрежата. Например всички маршрути в Vyatta се изпълняват от демона зебра или пък мрежовите интерфейси се конфигурират с ip address а не с ifconfig и така нататък. Определено операцията която извърших имаше смисъл и усетих удовлетворение когато видях колко малко ресурси харчи и с каква лекота работи новият маршрутизатор …
