Глобальні налаштування DHCP сервера

set system services dhcp-local-server pool-match-order external-authority
set system services dhcp-local-server pool-match-order ip-address-first
set system services dhcp-local-server no-stale-timer-refresh
set system services dhcp-local-server stale-timer 30

Наступний блок це власне налаштування DHCP сервера. Рекомендую зразу записувати різні кейси в окремі групи - так легше розуміти

set system services dhcp-local-server group IPOE_QINQ access-profile IPOE_QINQ
set system services dhcp-local-server group IPOE_QINQ interface ae1.0

в даному блоці є 3 змінні без яких нічого не запрацює:

• dynamic-profile dhcp-profile
• access-profile IPOE_QINQ
• interface ae1.0

їх треба описати

Всі пули іп адрес, які можуть бути видані абоненту потрібно описати наступним чином

set access address-assignment pool cvlan10_128-17 family inet network 10.10.128.0/17
set access address-assignment pool cvlan10_128-17 family inet range ip low 10.10.128.11

set interfaces lo0 unit 0 family inet address 10.10.128.2/32

перші 10 іп з кожного пулу я резервую для майбутніх БРАСів. В мене використовується QinQ технологія, тому немає сенсу робити пули меншими - описую весь пул за раз.

### - не хороша ідея на одному влані тримати і pppoe і dhcp абонів - dual-access на роутерах вам почнуть снитись в страшних снах
