ну а за етим маршрутизатором все както мутно работает, причем когда тестили то у чаловека через 5-10 мин только звук появился и на домовой циске вяло от него идут запросы.

 

Как можно продиагностировать в чем трабла?

 

еще вопрос в следующем, второй PIM должен маршруты сразу строить к источнику или по запросу igmp с дома?
