The hosts receive multicast traffic as follows:
– Host 1 receives multicast traffic for groups (*, 225.10.0.11), (22.10.0.13,
225.10.0.13)
– Host 2 receives multicast traffic for groups (*, 225.10.0.11), (*, 230.0.2.1),
(22.10.0.13, 225.10.0.13), (22.10.0.3, 230.0.2.3)

Prerequisites

Configured VLANs.
•
Enabled IGMP.
•
Configured a switch or Mrouter as the Querier.
•
Identified the IGMP version(s) you want to enable.

Configuration
This section provides the configuration details of the switches shown in Figure 20.
Switch A Configuration
1. Configure VLANs and tagging.
2. Configure an IP interface with IPv4 address, and assign a VLAN.
3. Configure STP. Assign a bridge priority lower than the default bridge priority to
enable the switch to become the STP root in STG 2 and 3.
