Всем привет.
Изучаю OSPF. В Cisco packet tracert построил вот такую схему:
завел ospf в area 0 все узлы.
Но как только рву связь мезжу двумя роутерами на обоих пропадают все ospf маршруты вообще.
Это баг пэкет трейсера, или я что то не так настроил ?
Вот что происходит когда рву связь между router0 и router1, лог с router1 :

Остальных не вижу смысла выкладывать, так как тоже самое, только анонсы чуть другие.
Вот если что сама лаба для cisco packet tracer 7.0
