Example: Configuring non-scoped IPv6 PIM-SM

Network configuration

OSPFv3 runs on the network.
VOD streams are sent to receiver hosts in multicast. The receivers of different subnets form stub networks, and a minimum of one receiver host exist in each stub network. The entire IPv6 PIM-SM domain contains only one BSR.
Host A and Host C are multicast receivers in the stub networks N1 and N2.
Specify VLAN-interface 102 on Switch E as a C-BSR and a C-RP. The C-RP is designated to the IPv6 multicast group range FF0E::101/64. Specify VLAN-interface101 of Switch D as the static RP on all the switches to back up the dynamic RP.
MLDv1 runs between Switch A and N1, and between Switch B, Switch C, and N2.

Procedure

Assign an IPv6 address and prefix length to each interface, as shown in Figure 121. (Details not shown.)
Configure OSPFv3 on all switches in the IPv6 PIM-SM domain. (Details not shown.)
Enable IPv6 multicast routing, MLD, and IPv6 PIM-SM:
# On Switch A, enable IPv6 multicast routing.
```
<SwitchA> system-view
[SwitchA] ipv6 multicast routing
[SwitchA-mrib6] quit
```
# Enable MLD on VLAN-interface 100 (the interface that is connected to the stub network).
```
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] mld enable
[SwitchA-Vlan-interface100] quit
```
# Enable IPv6 PIM-SM on other interfaces.
```
[SwitchA] interface vlan-interface 101
[SwitchA-Vlan-interface101] ipv6 pim sm
[SwitchA-Vlan-interface101] quit
[SwitchA] interface vlan-interface 102
[SwitchA-Vlan-interface102] ipv6 pim sm
[SwitchA-Vlan-interface102] quit
```
# Enable IPv6 multicast routing, MLD, and IPv6 PIM-SM on Switch B and Switch C in the same way Switch A is configured. (Details not shown.)
# Enable IPv6 multicast routing and IPv6 PIM-SM on Switch D and Switch E in the same way Switch A is configured. (Details not shown.)
Configure C-BSRs, C-RPs, and static RPs:
# On Switch E, configure the service scope of RP advertisements.
```
<SwitchE> system-view
[SwitchE] acl ipv6 basic 2005
[SwitchE-acl-ipv6-basic-2005] rule permit source ff0e::101 64
[SwitchE-acl-ipv6-basic-2005] quit
```
# Configure VLAN-interface 102 as a C-BSR and a C-RP, and configure VLAN-interface 101 of Switch D as the static RP.
```
[SwitchE] ipv6 pim
[SwitchE-pim6] c-bsr 1003::2
[SwitchE-pim6] c-rp 1003::2 group-policy 2005
[SwitchE-pim6] static-rp 1002::2
[SwitchE-pim6] quit
```
# On Switch A, configure VLAN-interface 101 of Switch D as a static RP.
```
[SwitchA] ipv6 pim
[SwitchA-pim6] static-rp 1002::2
[SwitchA-pim6] quit
```
# Configure a static RP on Switch B, Switch C, and Switch D in the same way Switch A is configured. (Details not shown.)
