В этом задании необходимо настроить перераспределение маршрутной
информации из протокола RIP в протокол OSPF.
Шаг 1
Посмотрите таблицы маршрутизации на центральном маршрутизаторе,
маршрутизаторах уровня распределения и уровня доступа. Какие протоколы

Задание 2. Управление перераспределяемой маршрутной информацией
В этом задании необходимо запретить распространять маршрутную
информацию о логических интерфейсах маршрутизаторов R2-R7 на
центральный маршрутизатор.
Шаг 1
Настройте на маршрутизаторе R2 список доступа, описывающий его
логический интерфейс, а также маршрутизаторов R4 и R5. Аналогичный
список доступа настройте на маршрутизаторе R3.
Шаг 2
Сделайте необходимые настройки в процессе маршрутизации OSPF на
маршрутизаторах R2 и R3, для того чтобы они не производили
перераспределение маршрутной информации об описанных логических
интерфейсах в протокол OSPF.
Шаг 3
Проверьте доступность с маршрутизатора R1 логических интерфейсов
маршрутизаторов R2-R7.
r1#ping 10.95.1.4
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.95.1.4, timeout is 2 seconds:
.....
Шаг 4
Посмотрите таблицу маршрутизации на маршрутизаторе R1.
