Почему не работает ospf маршрутизация через GRE/IPSEC в Juniper?

Question

[cyxer]

Добрый день, настроил gre между 2 Juniper srx. Ipsec и gre работают и шифруется. OSPF Hello пакеты проходят. Есть маршруты в таблице. пингует адреса туннеля, но как только хочу пингануть локалку то появляются лосы. Помогите пожалуйста
