Здравствуйте, есть 2 роутера cisco 29XX, между ними поднят nhrp, первый в режиме хаба, второй спок. В dmvpn поднят ospf и вижу что с хаба на спок приходит ненужный маршрут, не пойму почему такое происходит. Вот конфиг хаба:

Т.е. он по ospf в dmvpn зону backbone 0 пересылает маршруты из area 2 и соотвественно сети указанные в router ospf 11.
На споке конфиг:

Но на споке при поднятом ospf backbone 0 вижу маршрут от хаба:
O E2 X.X.26.160/29 [110/20] via 192.168.35.1, 00:04:59, Tunnel1
эта сеть закреплена на интерфейсе GigabitEthernet0/1 хаба, который не участвует в ospf.
Как такое может быть тогда?
