Лабораторная работа CCNA по теме PPP. Данная лабораторная работа может быть выполнена на реальном оборудовании или в Cisco Packet Tracer. Все необходимые действия указаны по порядку их выполнения. Для начала выполнения лабораторной работы необходимо соединить физическую сеть в соответствии со схемой сети или построить соответствующий проект в Cisco Packet Tracer. Сразу после схемы сети в таблице указана схема адресация, которую нужно применять только тогда, когда это будет явно указано в тексте лабораторной работы.
