5.17.2 IGMP snooping
IGMP Snooping is used in multicast networks. The main task of IGMP Snooping is the provisioning of
multicast traffic only for those ports, that have requested it.
IGMP Snooping can be used only in the static VLAN group. IGMP supported versions—
IGMPv1, IGMPv2, IGMPv3.
To activate IGMP Snooping, the 'bridge multicast filtering' function should be enabled (see
Section 'Multicast addressing rules').
Identification of ports with connected multicast routers is based on the following events:
– IGMP requests were received through the port
– Protocol Independent Multicast (PIM/PIMv2) protocol packets were received through the port
– Multicast routing packets of Distance Vector Multicast Routing Protocol (DVMRP) were received
through the port
– MRDISC protocol packets were received through the port
– Multicast Open Shortest Path First (MOSPF) protocol packets were received through the port
