Question 34

How does IGMP snooping eliminate multicast flooding on the LAN?

  1. The switch populates multicast source addresses into the forwarding table
  2. The switch acts as an IGMP proxy for the receiver
  3. The switch inspects IGMP messages between receivers and routers and populates the forwarding table with active multicast group addresses
  4. The switch inspects all multicast traffic between receivers and routers and populates the forwarding table with active multicast group addresses
