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

stand-plan

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

Host-4	Eth1	172.16.4.2/24	Leaf-3	Eth2	172.16.4.1/24

loopback table

Device	Loopback ip
Spine-1	192.168.1.1
Spine-2	192.168.1.2
Leaf-1	192.168.2.1
Leaf-2	192.168.2.2
Leaf-3	192.168.2.2

Примечания

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.

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.
