Network requirements
• As shown in Figure 204 , Router A connects to a multicast source (Source) through Ethernet 1/2,
and to Switch A through Ethernet 1/1.
• The multicast source sends multicast data to group 224.1.1.1. Host A is a receiver of the multicast
group.
• IGMPv2 runs on Router A and IGMP snooping version 2 runs on Switch A.
• The function of dropping unknown multicast packets is enabled on Switch A to prevent Switch A
from flooding multicast packets in the VLAN if no corresponding Layer 2 forwarding entry exists.
• The fast leave function is enabled for GigabitEthernet 1/0/3 on Switch A to improve bandwidth
and resource usage.
