[e-nsp] VLAN without IGMP snooping and multicasts

[Marcin Kuczera]

hello,

we have a customer who has some strange devices transmitting "fixed" 
multicast stream without using IGMP requests in a regular way.
So we had to turn off IGMP snooping on that vlan, otherwise transmission 
was extinguished after IGMP timers expire.
I'am not arguing with these devices, they transmit DVB-T MUX signal in 
their own, properitary way.

However, because it passes EAPS ring, I have noticed that this stream is 
also broadcasted to backup port of EAPS ring.

So my question is - is it correct that multicasts when IGMP snooping is 
off are broadcasted instead of using regular FDB ?

Switches: Summit-X650-24x
Soft: ExtremeXOS version 15.3 series
