What are IGMP packets?
IGMP is acronym for Internet Group Management Protocol. IGMP is a communication protocol used by hosts and adjacent routers for multicasting communication with IP networks and uses the resources efficiently to transmit the message/data packets.
What are the message types used in IGMP?
IGMP Message Types
| Message Type | Description |
