Hi,
I've setup a small lab to experiment igmp snooping of bridge in routeros.
Here is my simple setup:
All devices are CHR v6.48.1, where on 'Switch' I have setup bridge that bridges R1, R2 and R3 together. IGMP snooping on the bridge is enabled.
On both R1 and R2, I enabled OSPF (such that it starts generating multicast traffic) while on R3 OSPF is disabled.
I did wireshark capture on the link between 'Switch' and 'R3', it seems that OSPF hello packet is forward to R3 as well, am I correct to assume that multicast traffic in this case is flooded across the network? Will igmp snooping prevent multicast traffic being flooded to whole network?
Thanks!
