Задача получить DHCP на PC1 (CentOS7), в сети настроены VLAN VLAN100 - MGT 172.16.10.0/24 VLAN200 - DATA 172.16.20.0/30 VLAN300 - OFFICE 30.30.30.0/24 Trunk's созданы и работают через VTP.
На HQ1 (Router) настроил DHCP pool с Network 30.30.30.0/24 На PC1 пытаюсь получить DHCP, и вижу (WireShark) что HQ1 получает DHCP Discovery, но не отвечает. Вывод команды (sh ip dhcp server statistics) говорит о том же:
