How can you avoid flooding of multicast frames in a Layer 2 network?

  • Disable unknown multicast flooding
  • Enable multicast storm control
  • Enable IGMP snooping
  • Enable control plane policing

Explanation: IGMP snooping, defined in RFC 4541, examines IGMP joins sent by receivers and maintains a table of interfaces to IGMP joins. When a switch receives a multicast frame destined for a multicast group, it forwards the packet only out the ports where IGMP joins were received for that specific multicast group. This prevents multicast traffic from flooding in a Layer 2 network.
