IGMP
This category includes the IGMP protocol.
IGMP is used by hosts and routers to dynamically register and discover multicast group
membership. Attacks on the IGMP protocol usually target a vulnerability in the multicast
routing software/hardware used, by sending specially crafted IGMP packets.
You can configure how IGMP attacks should be handled.
