Chapter 4 Common Multicast Configuration

4.1 Overview
Common multicast configuration tasks are the common contents of the multicast group
management protocol and the multicast routing protocol. You must enable the common
multicast configuration on the switch before enabling the two protocols.
Common multicast configuration includes:
Configuring limit on the number of route entries: when the multicast routing
protocol is configured on a switch, plenty of multicast route entries will be sent to
upstream Layer 3 switches or routers. In order to prevent plenty of multicast route
entries from consuming all the memory of the Layer 3 switches or routers, you can
configure limit on the number of route entries to prevent too many route entries
from being sent to Layer 3 switches or routers.
Configuring suppression on the multicast source port: 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 suppression on the multicast
source port 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.
Clearing the related multicast entries: through clearing the related multicast
entries, you can clear the multicast route entries saved in the memory of the Layer
3 switches or routers to release the system memory.
