on the VLAN
Caution:
Before enabling IGMP Snooping in a VLAN, be sure to enable IGMP Snooping
globally in system view; otherwise the IGMP Snooping settings will not take effect.
If IGMP Snooping and VLAN VPN are enabled on a VLAN at the same time, IGMP
queries are likely to fail to pass the VLAN. You can solve this problem by configuring
VLAN tags for queries. For details, see
Messages.

2.2.2 Configuring the Version of IGMP Snooping

With the development of multicast technologies, IGMPv3 has found increasingly wide
application. In IGMPv3, a host can not only join a specific multicast group but also
explicitly specify to receive or reject the information from a specific multicast source.
Working with PIM-SSM, IGMPv3 enables hosts to join specific multicast sources and
groups directly, greatly simplifying multicast routing protocols and optimizing the
network topology.
