along the path of Switch A—Switch B—Switch C. When this path is blocked, a minimum of one
MLD query-response cycle must be completed before IPv6 multicast data flows to the receivers
along the path of Switch A—Switch C. In this case, the multicast delivery is interrupted during
the process. For more information about the STP, see Layer 2—LAN Switching Configuration
Guide.
Configure GigabitEthernet 1/0/3 on Switch A as a static router port. Then, IPv6 multicast data
can flow to the receivers nearly uninterrupted along the path of Switch A—Switch C when the
path of Switch A—Switch B—Switch C is blocked.

Configuration procedure
1. Assign an IPv6 address and prefix length to each interface, as shown in Figure 78. (Details not
shown.)
2. Configure Router A:
# Enable IPv6 multicast routing.
<RouterA> system-view
[RouterA] ipv6 multicast routing
[RouterA-mrib6] quit
# Enable MLD on GigabitEthernet 1/0/1.
[RouterA] interface gigabitethernet 1/0/1
[RouterA-GigabitEthernet1/0/1] mld enable
[RouterA-GigabitEthernet1/0/1] quit
# Enable IPv6 PIM-DM on GigabitEthernet 1/0/2.
[RouterA] interface gigabitethernet 1/0/2
[RouterA-GigabitEthernet1/0/2] ipv6 pim dm
[RouterA-GigabitEthernet1/0/2] quit
3. Configure Switch A:
# Enable MLD snooping globally.
<SwitchA> system-view
[SwitchA] mld-snooping
