Similarly, with IGMP Snooping not enabled on the SU/End Point B, the multicast data is transmitted irrespective of whether
the multicast group address is a member of the multicast group table maintained in each SU/End Point B. With IGMP
Snooping enabled, the SU/End Point B transmits the data to the host only when the multicast group address is a member of
the multicast group table, else drops the packet.
IGMP Snooping is of 2 kinds:
Active: Active IGMP Snooping listens to IGMP traffic and filters IGMP packets to reduce load on the multicast router.
Passive: Passive IGMP Snooping simply listens to IGMP traffic and does not filter or interfere with IGMP.
