Почему в таблице маршрутизации пропали все маршруты протокола RIP,
а вместо них появились маршруты протокола OSPF? Почему маршруты
протокола EIGRP не указывают дальше одного перехода?
Шаг 4
Посмотрите таблицу топологии протокола EIGRP.

Почему таблица топологии не содержит всей топологической
информации?
Шаг 5
Измените административное расстояние для протокола RIP на его
административное расстояние по умолчанию на всех остальных
маршрутизаторах стенда.
Шаг 6
Посмотрите таблицу топологии протокола EIGRP.
