Subject: What is the correct way to install an L2 multicast route into a bridge?
Date: Wed, 8 Jul 2020 12:04:54 +0300	[thread overview]
Message-ID: <20200708090454.zvb6o7jr2woirw3i@skbuf> (raw)

Hi,

I am confused after reading man/man8/bridge.8. I have a bridge br0 with
4 interfaces (eth0 -> eth3), and I would like to install a rule such
that the non-IP multicast address of 09:00:70:00:00:00 is only forwarded
towards 3 of those ports, instead of being flooded.
The manual says that 'bridge mdb' is only for IP multicast, and implies
that 'bridge fdb append' (NLM_F_APPEND) is only used by vxlan. So, what
is the correct user interface for what I am trying to do?

Thank you,
-Vladimir
