An incident happened on November 21th between 3:03pm and 3:24pm. A Layer 2 loop was generated between two members. Protections to limit broadcast traffic worked as expected.
However multicast filters were not configured in the same way to shape the traffic.
Since then, actions have been taken to reinforce multicast filters. Globally, all the filters have been reinforced, particularly with the partner IXPs.
A web page is now available describing authorised traffic on France-IX platform.
A campaign will be launched in January 2015 to contact the members who do not comply to the defined rules
