Упражнение 1: на каждом
маршрутизаторе "уронить" один
последовательный интерфейс (shutdown). Соседи
должны определиыь, какой именно
интерфейс был выключен.
Упражнение 2: привести все в порядок.
Выключить коммутатор Frame Relay (c2522).
Перестроить таблицы
маршрутизации так, чтобы сеть
оставалась связной. 
  
Используемый стенд: стенд 1.
Используется
конфигурация из
лабораторной работы 1.3.1.
Упражнение: закрыть доступ по telnet в "свою"
подсеть, за
исключением доступа с
персоналок.

Упражнение: уменьшить скорость Frame Relay до 4800,
запустить на PC команду
════════════ telnet
адрес-соседнего-маршрутизатора 19 
где соседний - по часовой стрелке, 19 - порт для
сервиса chargen. Убедиться, что канал
загружен и работать
невозножно. Снять задачу и
настроить алгоритм
обработки очередей так, чтобы chargen никому не
мешал.

интерфейс межу c2500a и c2500b (делаем на c2500a: conf terminal;interface
serial 0;shutdown).
Наблюдаем за изменение
топологии в таблицах OSPF.
Восстанавливаем нтерфейс и
отмечаем время
сходимости OSPF. 
  
Используемый стенд: стенд 3.
Используется
конфигурация из
лабораторной работы 3.1.4
(упражнение 1, EIGRP) 
. 
Упражнение 1: разбиение
автономной системы на 3 (a - AS100, b - AS200, c - AS300)
Предварительные действия: убрать
маршрутизацию EIGRP.
Действия по шагам (вместо n и m должны быть
соответствующие числа):
    
    c2500x#debug ip eigrp 
    c2500x#debug ip bgp
  
    
    c2500x#configure terminal
  
    
    c2500x(configure)# no router eigrp 109
