# lab01-basic-CLOS
### Задание
1.Соберете топологию CLOS, как на схеме.
2.Распределите адресное пространство для Underlay сети
3.Зафиксируете в документации план работ, адресное пространство, схему сети, настройки (если перенесли на оборудование)
### Схема стенда
Стенд делаем по принципу - хосты linux, leaf - frr, spine - arista
### Распределение адресного пространства для Underlay
План составлен с учетом 10.x.y.z, где x - номер DC, y - номер spine, z - по очереди для подключения leaf Адреса для хостов - 172.16.x.z/24, где x - номер leaf, z - по порядку адрес хоста, на leaf ip .1 Адреса loopback 192.168.a.b/32, где a - 1 для spine, 2 - для leaf, b - номер spine, leaf по порядку

#### Примечания
{% hint style="info" %}
### так как в явном виде не указано что делать с адресацией на хостовых машинах, а в качестве leaf и spine выступают роутеры, до настройки overlay адреса на хостах распределены из разных подсетей.
{% endhint %}
Когда поднимем overlay засунем все в одну подсеть чтобы эмулировать l2.
### Запуск лабараторной в среде netlab
Так как у самурая только путь, делаем все в netlab-tools.

Пинговать хосты или leaf между собой лишено смысла, т.к. нет маршрутов на устройствах.
