Лабораторная работа №1 Основные конфигурации маршрутизатора
Enter configuration commands, one per line. EndwithCNTL/Z.
После входа в режим конфигурации нужно задать имя хоста маршрутизатора 1 командой hostname
password Assign the privileged level password
secret Assign the privileged level secret
Устанавливаем пароли: допускающийся пароль ccnalab, который будет файлом конфигурации маршрутизатора и допустимый пароль cisco, который будет зашифрован.
router1(config)#enable password 123
router1(config)#enable secret cisco
Необходимо присвоить ip адрес для маршрутизатора 1 интерфейс Ethernet0(Ip адрес и маска даны в таблице).
router1(config-if)#ip address 160.10.1.1 255.255.255.0
%LINK-3-UPDOWN: Interface Ethernet0, changed state to up
Необходимо присвоить ip адрес для маршрутизатора 1 интерфейс Serial0. Для выхода из режима конфигурирования можно с помощью команды ctrl—z.
router1(config-if)#ip address 175.10.1.1 255.255.255.0
%LINK-3-UPDOWN: Interface Serial0, changed state to up
%LINK-3-UPDOWN: Interface Serial0, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0, changed state to down

Ввести logout чтобы выйти в пользовательский режим
Router con0 is now available
Press RETURN to get started.
Нажимаем ЕNTER и попадаем в пользовательский режим и печатаем enable для привилегированного режима, вводим секретный пароль cisco.
