The Internet Group Management Protocol (IGMP) Snooping function can improve bandwidth utilization and enhance network security and reliability.
IGMP Snooping
The Internet group management protocol (IGMP) Snooping technology is used to enhance the multicast management capability of Layer 2 switching equipment. This technology applies to data service boards that support Layer 2 switching. Based on the interception of Layer 3 IGMP packets, the Layer 2 multicast function is created and maintained, to prevent multicast packets from being broadcast in the Layer 2 equipment.
Configuring the IGMP Snooping Protocol
IGMP snooping increases resource utilization by forwarding multicast packets and increases network security by restricting user access.
