Приветствую! Столкнулся с проблемой: имеется маршрутизируемая сеть с OSPF в которой ходят multicast-каналы (технологическое видео) и ходят без проблем. Появилась необходимость прокинуть еще один канал видео и тут возникла проблема - траффик не ходит.
Для выяснения причин - настроена cisco1812 на "поиграться" со статической маршрутизацией и то же самое - данные не ходят.

существующие каналы( udp/rtp) ходят и по реальной схеме и по c1812 нормально.

В "плоской" сети этот источник смотрится нормально тем же самым VLC(udp://@239.255.0.1:12345/ ), а через роутеры - никак....
В чем может быть проблема?
