Мы пытаемся у себя настроить мультикаст на свиче DGS-3627G
Мультикаст приходит по интерфейсу iptv, а должен уходить на интерфейс users
На Сisco все работает. На DGS-3627G не получается.
(VLC)----->catalyst 3560(1) ------ > catalyst 3560(2) ------>DGS-3627G---> компьютер(10.10.30.2)
cat(1) vlan 444 - pim-sm (10.10.20.21)
cat(2) vlan 444 - pim-sm (10.10.20.22) RP-10.10.20.21
VLC(239.2.2.1)
Пробовали между DGS-3627G и компьютером ставить DES-3010G. Эффект тот же
Если подключаемся к любой из CISCO - то мультикаст работает
Перепробовали несколько десятков разных комбинаций.
Пробовали на прошивках: 2.50.B25, Build 2.52.B44, 2.50.B25
На DGS-3627G
