Дибров М.В., Кузьменко Н.Г., Журавлев А.А. Маршрутизаторы
Подождите немного. Документ загружается.
Объясните, почему на всех маршрутизаторах стенда таблицы
маршрутизации имеют одинаковое количество записей?
Задание 2. Управление процессом распространения суммарной
межзональной топологической информации.
В этом задании необходимо настроить процесс распространения
суммарной межзональной топологической информации с целью уменьшения
таблиц топологии и маршрутизации на внутренних маршрутизаторах зон
OSPF.
Шаг 1
Для оптимизации таблиц топологии и маршрутизации, настройте на
пограничных маршрутизаторах стенда распространение суммарной
топологической информации о зонах OSPF.
Шаг 2
Еще раз посмотрите таблицу топологии на маршрутизаторах стенда.

Видно, что после настройки распространения суммарной
топологической информации количество строк в таблицах топологии
маршрутизаторов резко сократилось.
Шаг 3
Посмотрите, как отразилось уменьшение таблиц топологии на
количество записей в таблице маршрутизации на маршрутизаторах стенда.

Маршрутизатор распространяет внешний маршрут 2 типа.
Шаг 4
Настройте центральный маршрутизатор на распространение маршрута
по умолчанию 1 типа, и посмотрите таблицу маршрутизации.

Лабораторная работа 8. Управление распространением
топологической информации в протоколе OSPF
Цель работы:
Изучить механизмы распространения топологической информации в
пределах домена маршрутизации OSPF.
Ограничить распространение топологической информации при помощи
тупиковых и полностью тупиковых зон OSPF.
Схема стенда:
Схема соединений маршрутизаторов в лабораторном стенде для
выполнения лабораторной работы № 8 представлена на рисунке 8.
