Hi,
Have been experimenting with bridged networking in order to connect VMs
located on separate physical machines. Unicast communication works fine but
multicast traffic in not being forwarded beyond the bridge. Looking at the code
am reaching the conclusion that bridge treats multicast traffic in same way as
broadcast, so why the multicast traffic is not flowing beyond the bridge. Also
does kernel tunable like mc_forwarding have any significance in this matter? On
the later version of linux 2.6.18 and after am finding this tunable as
read-only (and set to 0). The kernel being used has CONFIG_IP_MROUTE enabled
but its not running mrouted.
Regards Animesh
