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 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). 3 ТАБЛИЦЫ МАРШРУТИЗАЦИИ R1 Router#show ip route Codes: C - connected, S -
