Example: Configuring IPv6 BIDIR-PIM
Network configuration
As shown in Figure 123:
OSPFv3 runs on the network.
VOD streams are sent to receiver hosts in IPv6 multicast.
Source 1 and Source 2 send IPv6 multicast data to IPv6 multicast group FF14::101.
Host A and Host B are receivers of this IPv6 multicast group.
VLAN-interface 102 of Switch C acts as a C-BSR. Loopback 0 of Router C acts as the C-RP.
MLDv1 runs between Switch B and Host A, and between Switch D and Host B.

Procedure
Assign an IPv6 address and prefix length to each interface, as shown in Figure 123. (Details not shown.)
Configure OSPFv3 on the switches in the IPv6 BIDIR-PIM domain. (Details not shown.)
Enable IPv6 multicast routing, IPv6 PIM-SM, IPv6 BIDIR-PIM, and MLD:
# On Switch A, enable IPv6 multicast routing, enable IPv6 PIM-SM on each interface, and enable IPv6 BIDIR-PIM.

# On Switch B, enable IPv6 multicast routing.

# Enable MLD on the receiver-side interface (VLAN-interface 200).
[SwitchB] interface vlan-interface 200 [SwitchB-Vlan-interface200] mld enable [SwitchB-Vlan-interface200] quit
# Enable IPv6 PIM-SM on the other interfaces.

# On Switch C, enable IPv6 multicast routing, enable IPv6 PIM-SM on each interface, and enable IPv6 BIDIR-PIM.

# On Switch D, enable IPv6 multicast routing.

# Enable MLD on the receiver-side interface (VLAN-interface 300).
[SwitchD] interface vlan-interface 300 [SwitchD-Vlan-interface300] mld enable [SwitchD-Vlan-interface300] quit
# Enable IPv6 PIM-SM on the other interfaces.

On Switch C, configure VLAN interface 102 as a C-BSR, and loopback interface 0 as a C-RP for the entire IPv6 BIDIR-PIM domain.
