Enabling Multicast Routing; Configuring Limit On The Number Of Routing Entries - H3C S5600 SERIES Operation Manual

The multicast packet buffering feature should be enabled before multicast routing is enabled.

Enabling Multicast Routing

Follow these steps to enable multicast routing:
To do...
Enter system view
Enable multicast routing
To guard against attacks on any socket not in use, S5600 series provide the following functions to
achieve enhanced security:
The system opens the RAW Socket used for multicast routing only if multicast routing is enabled.
When you disable multicast routing, the RAW Socket used for multicast routing is also closed.
IGMP, PIM and MSDP configurations can be performed or can take effect only if multicast routing has
been enabled.

Configuring Limit on the Number of Routing Entries

Multicast routing entries specify the interfaces through which multicast packets are sent to multicast
group members. Too many multicast routing entries can exhaust the router's memory and thus result in
lower router performance. Therefore, the number of multicast routing entries should be limited.
