Доброе время суток!

 

Столкнулся со странной работой коммутатора ZTE ZXR10 5928FI - при транзите через него мультикаста в VLANа изменяется Querier (если так можно сказать):

- в обход ZTE:

10.40.89.79 - неизвестный Querier

 

Эффект остается при отсечении уровня раздачи мультикаста клиентам.

ZTE работает как Level2 коммутатор и агрегатор оптических линков.

 

Клиенты работающие транзитом через ZTE жалуются на замирание картинки каждые 5 минут, трансляция возобновляется при передергивании канала на клиентском оборудовании.

 

Помогите настроить транзит мультикаста!
