Configuration
Network requirements
■ As shown in Figure 178, Router A connects to an IPv6 multicast source (Source)
through GigabitEthernet 1/0/2, and to Switch A through GigabitEthernet
1/0/1.
■ MLD is to run on Router A, and MLD Snooping is to run on Switch A, Switch B
and Switch C, with Router A acting as the MLD querier.
