Just an explanation to distinguish processing of layer 3 multicast
packets (by routers) from layer 2 multicast frames (by bridges). Due to
the fact that the multicast MAC addresses are not permitted in the
Ethernet frame as source addresses, multicast MAC addresses can not be
learnt by the bridges, so the processing of multicast addresses by
bridges consists in broadcasting, flooding frames in all but source
port, instead of forwarding them only by ports where these addresses
were learnt.
Excuse me if it sounds a bit "academic".

Hi,
I checked archives but I haven't found this subject before.
Does bridge support multicast or not? I checked the code and it would seem
that bridge will flood multicast frames to all but source port.

Yes, that is what multicast is.
