Chapter 3 Common Multicast Configuration
3.1 Overview
Common multicast configuration tasks are the common contents of multicast group
management protocol and multicast routing protocol. You must enable the common
multicast configuration on the switch before enabling the two protocols.
In the network, some users may set up multicast servers privately, which results in the
shortage of multicast network resources and affects the multicast bandwidth and the
transmission of valid information in the network. You can configure the suppression on
the multicast source port feature to filter multicast packets on the unauthorized
multicast source port, so as to prevent the users connected to the port from setting up
multicast servers privately.
