Всё работало пока что-то сам не сделал... как говорится хочешь улучшить - сохрани как было :)

 

Есть схема: uplink - cisco7609 - (vlan8) - dlink3627 - (vlan8) - dlink3552 - приставка.

Трогался только 3627.

Кошка к аплинку по mbgp, на ней pim-sparse. 3552 - multicast vlan8.

 

3627 был настроен только с igmp-snooping мультикаст вланом.

 

Решил перевести его на pim (порекомендовал uplink). С тех пор у 3627 есть только:

Command: show igmp_snooping group

Что выглядит правильным за исключением момента что в мемберах только исходящие порты, а src порт 27 отсутствует. Ну и как результат:

Command: show igmp_snooping forwarding

Total Entries : 0

 

При этом:

Command: show igmp group

Если у вас DGS не маршрутизирует - PIM вам не нужен.

Либо скидывайте на него абонентские шлюзы (это правда не очень хорошая идея, ибо L3 на нем баговый)

Либо верните в зад igmp_snooping

[borcat]

Таки разобрались (ещё на прошлой неделе). Было: при поднятии mbgp сессии почему-то не ходил мультикаст... решилось принудительным сбросом сессии с ОБЕИХ сторон. С одной не помогало.

Посе прибил PIM и сделал как было.

Всем спасибо за участие.
