the default version of IGMP that FC6 used last November was Ver 2, multicast setup to Cisco routers worked great. The last install I did of FC6 in April 2007 apparently changed the default version of IGMP to ver 3. multicast no longer works to these FC6 servers and v3 is the only thing I can come up with. Regardless, how do I set IGMP back to use ver 2 as its default version?
