Нубский вопрос про пересечение адресов

[RN3DCX]

Собственно хочу создать сабинтефейс с адресом 10.0.0.254 и маской 255.255.255.0

Но маршрутизатор говорит, что данная сеть уже арбайтен!?

 

Нубский вопрос, чё не так?

Ведь везде /24 маска.

Сначало указываем тип саба, потом вешаем IP.

Стыдно конечно признать, что дело было не в бабине...

prolan, спасибо!
