METHOD, SWITCHING DEVICE AND SYSTEM FOR ENABLING MULTICAST FORWARDING

摘要

Embodiments of the present invention relates to the field of IP communication technologies, and disclose a method, a switching device and a system for enabling multicast forwarding to implement flexibly networking and enable the multicast proxy function correctly. The method includes: receiving a multicast protocol message; determining a sender of the multicast protocol message; transmitting the multicast protocol message transparently if the sender of the multicast protocol message is a routing device or switching device; and terminating the multicast protocol message according to a multicast proxy function if the sender of the multicast protocol message is a host of a multicast user.
