IGMP Snooping

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.
