Thanks, that is a very useful link!

Also, it should be stressed that the CGMP is Cisco-proprietary protocol and must be supported both by switch AND router. In CGMP, it is the router that controls the switch using CGMP. Without a CGMP-compliant router, the switch will not provide any optimized multicast delivery, and will flood all multicast packets out every port except the inbound port.

Best regards,
