An exhaustive tutorial of IP multicasting and troubleshooting is beyond the scope of this document. If you are having problems with multicast discovery, ensure that your operating system is configured to provide IP multicasting support. Most modern versions of Linux* and Windows* provide this support, however it might be disabled. Multicast discovery does not work unless IP multicasting is enabled by the operating system. Routing misconfiguration on the system can also lead to problems with multicast discovery.
