> Hello,
> I'm doing some testing in a network with multiple routers and loops.

> Everything seems to be working fine, the hosts connected to the three
> subnets see each other just fine and there is no packet storm due to the
> loop.
> My question to the developpers is why isn't there a problem? since the
> reflector just forwards the multicast packets and changes the source
> address the queries should loop infinitetly, right?
> So is there a mechanism to stop the packet storm so it's ok to use the
> reflector option in looped networks, or it should be avoided?
> Kind regards,
