ВВЕДЕНИЕ
Компьютерная сеть (вычислительная сеть, сеть передачи данных) — система связи компьютеров и/или компьютерного оборудования (серверы, маршрутизаторы и другое оборудование). Для передачи информации могут быть использованы различные физические явления, как правило — различные виды электрических сигналов, световых сигналов или электромагнитного излучения.
Целью является разработка такой сети.
ЗАДАНИЕ
В среде Cisco Packet Tracer необходимо разработать сеть, состоящую из 6 подсетей, 11 маршрутизаторов. В каждой подсети должно быть не менее 8 компьютеров. В общей сети необходимо реализовать 4 статических маршрута.
МОДЕЛИРОВАНИЕ СЕТИ
Для создания сети, кроме маршрутизаторов, понадобятся коммутаторы (свитчи) для соединения компьютеров в подсети. Их понадобится 7 штук. Коммутаторы проще по устройству, и на них накладывается более простые задачи. Поэтому их конфигурировать не надо. На рисунке 1.1 представлен вид интерфейса коммутатора, используемого в работе. Все 7 коммутаторов имею одинаковую физическую реализацию.

Физическая реализация маршрутизаторов представлена на рисунке 1.2. Все 11 коммутаторов имею одинаковую физическую реализацию.
Физическая реализация компьютеров представлена на рисунке 1.3. Все компьютеры имею одинаковую физическую реализацию.

НАСТРОЙКА КОМПОНЕНТОВ
Приступим непосредственно к настройке. Начнем с маршрутизаторов. Для них нам необходимо для каждого активного порта указать уникальный IP-адрес — сетевой адрес узла в компьютерной сети, построенной по протоколу IP. Для этого нам необходимо: клик на роутер -> Config -> Intarface и в появившемся окне заполнить IP Address и Subnet Mask (рис 2.1.).
Теперь настроим компьютеры. Для них нужно указать IP-адрес, маску подсети и адрес шлюза: клик на компьютер -> Config -> Intarface и в появившемся окне заполнить IP Address и Subnet Mask. В поле Default Gateway пишем адрес ближайшего маршрутизатора (рис. 2.2).

Названия и адреса устройств приведены в Таблице 1.

Созданная и настроенная сеть показана на рисунке 2.3.
Статические маршруты определены следующим образом:
1. из сети 125.10.10.0/24 в сеть 100.1.1.0/16 через R2, R6,R4;
2. из сети 119.20.65.0/21 в сеть 10.10.4.0/20 через R9, R5, R1, R2, R6;
3. из сети 168.55.15.0/24 в сеть 125.10.10.0/24 через R11, R10, R9, R8, R7, R6, R2;
4. из сети 172.16.11.0/24 в сеть 100.1.2.0/16 через R5, R1, R2, R3.
Статическая маршрутизация задается командой:
(config)#ip route (сеть назначения) (маска) (адрес следующего участка или интерфейс выхода).
