Маршрутизатор r4 получил маршрут по умолчанию, но количество
записей в таблице маршрутизации не изменилось.
Шаг 3
Внимательно изучите топологию стенда и посмотрите, какие группы
маршрутов к сетям могут быть заменены суммарными маршрутами на каждом
из маршрутизаторов стенда. Изучение топологии сети следует начинать с
уровня доступа. Назначьте распространение суммарных маршрутов RIP с
интерфейсов, через которые они могут распространяться.
Шаг 4
Посмотрите полученные таблицы маршрутизации. Перед просмотром
таблиц маршрутизации воспользуйтесь командой clear ip route *, которая
очистит старую таблицу маршрутизации и после этого будет построена новая.
33
Необходимость применения данной команды обусловлена инертностью
протокола RIP.

Лабораторная работа 4. Базовая настройка протокола EIGRP
Цель работы:
Произвести базовую настройку и изучить механизмы
функционирования протокола маршрутизации EIGRP. Настроить
аутентификацию соседних маршрутизаторов при обмене служебными
пакетами.
Схема стенда:
Схема соединения маршрутизаторов в лабораторном стенде для
выполнения лабораторной работы № 4 представлена на рисунке 4.

Задание 1. Запуск процесса маршрутизации EIGRP.
В этом задании необходимо провести запуск протокола маршрутизации
EIGRP на маршрутизаторах лабораторного стенда.
Шаг 1
Запустите на маршрутизаторах стенда протокол маршрутизации EIGRP
в автономной системе с номером 200. Задайте сети, которые будут
участвовать в процессе маршрутизации. По умолчанию отключите рассылку
обновлений маршрутной информации со всех интерфейсов маршрутизатора.
Включите рассылку обновлений только на необходимых интерфейсах.
Отключите функцию автоматического суммирования маршрутов.
Шаг 2
Убедитесь в том, что на маршрутизаторах запущен протокол
маршрутизации EIGRP AS200 и в нем участвуют сети, которые были описаны.
