Здравствуйте, коллеги. С недавних пор провайдер стал отдавать оную опцию по dhcp. Провел исследование, и обнаружил, что при получении адреса во время старта системы маршрут не применяется, хотя network-manager видит, что опция прилетела, а если вручную дернуть dhclient командой dhclient -r eth0 , то маршрут появляется.
И так вопрос, почему при старте системы игнорится опция?

P.S. знаю, что маршрут отдается в мою сеть. Сделано это в из-за использования сегментации трафика на коммутаторах провайдера.
