Как настроить маршрутизацию на основе политик при добавлении маршрутизатора?

Я использовал 2WAN с текущим CCR1016. Чтобы связать с роутером, нужно добавить еще один роутер здесь, только терминал. Думаю, можно настроить с помощью маршрутизации на основе политик в этом случае, но интересно, есть ли способ добавить, не ломая текущие настройки?
