HI!

Проблема с mrouted

Суть:

Что имеем: сервер FreeBSD 6.1

server# ifconfig
rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        options=8<VLAN_MTU>

На сервере установлен vlc и запущенo 2 видеопотока в мультикасте
vlc -d /usr/local/etc/vlc/film/film.avi --sout udp:224.0.0.0 --ttl 3 --loop
vlc -d /usr/local/etc/vlc/film/film2.avi --sout udp:225.0.0.0 --ttl 3 --loop

Что получилось:
в 1-ой сети с помощью того же vlc открываем и смотрим без проблем видеопоток 224.0.0.0 и 225.0.0.0

если же на сервере запускаем vlc так,
vlc -d /usr/local/etc/vlc/film/film.avi --sout udp:224.0.0.1 --ttl 3 --loop
vlc -d /usr/local/etc/vlc/film/film2.avi --sout udp:224.0.0.4 --ttl 3 --loop

то так же смотрим в 1-ой сети все ОК
но вывод tcpdump'а уже другой

но при любом раскладе
во 2-ой, 3-ей и 4-ой сетях видеопотока нет

смотрим на самом сервере

аналогично и на остальных других интерфейсах rl2 и rl3

^C20:56:03.661 mrouted version 3.9-beta3+IOS12 exiting
server#

Откуда появляются 224.0.0.1 224.0.0.2 и 224.0.0.4 ????? Мультикаст-то ведь запускаю на 224.0.0.0 и 225.0.0.0 !!!!

Что за фигня? Как передать мультикаст в другие сети??
man mrouted ничего вразумительного не дал :((

Какие будут соображения, коллеги?
