Enabling Ip Multicast - Huawei Quidway S9300 Configuration Manual - Multicast

2 IGMP Configuration
You must enable IP multicast routing before configuring IGMP. IP multicast routing is the
prerequisite of configuring all multicast functions. If IP multicast routing is disabled, the
multicast-related configurations cannot take effect.
IGMP needs to be enabled on the VLANIF interface that is connected to the host. The matching
IGMP version needs to be configured on the S9300 and host because the IGMP messages vary
according to version. The later version on the S9300 side is compatible with the earlier version
on the host side. Other configurations can be performed only after IGMP is enabled.
The host where the IGMP is run responds to the IGMP Query message of the S9300. If the host
gives no response and the operation times out, the S9300 considers that the multicast group does
not contain any member on the network segment and cancels data forwarding.
To enable hosts on the network segment of the interface to join the specified groups and receive
packets from the groups, you can set an ACL on the related interface to limit the range of groups
that the interface serves.

Context
The IP multicast function is the prerequisite of configuring other multicast protocols. Do as
follows on the S9300 connected to a host.
