Example: Configuring admin-scoped PIM-SM
Network configuration
As shown in Figure 57:
OSPF runs on the network.
VOD streams are sent to receiver hosts in multicast. The entire PIM-SM domain is divided into admin-scoped zone 1, admin-scoped zone 2, and the global-scoped zone. Switch B, Switch C, and Switch D are ZBRs of the three zones, respectively.
Source 1 and Source 2 send different multicast data to the multicast group 239.1.1.1. Host A receives the multicast data only from Source 1, and Host B receives the multicast data only from Source 2. Source 3 sends multicast data to multicast group 224.1.1.1. Host C is a multicast receiver for the multicast group 224.1.1.1.
VLAN-interface 101 of Switch B acts as a C-BSR and a C-RP for admin-scoped zone 1, and VLAN-interface 105 of Switch D acts as a C-BSR and a C-RP for admin-scoped zone 2. Both of the two interfaces are designated to multicast group range 239.0.0.0/8. VLAN-interface 109 of Switch F acts as a C-BSR and a C-RP for the global-scoped zone, and is designated to all the multicast groups that are not in the range 239.0.0.0/8.
IGMPv2 runs between Switch A, Switch E, Switch I, and the receivers that directly connect to them, respectively.

Procedure
Assign an IP address and subnet mask to each interface, as shown in Figure 57. (Details not shown.)
Configure OSPF on all switches in the PIM-SM domain. (Details not shown.)
Enable IP multicast routing, and enable IGMP and PIM-SM:
# On Switch A, enable IP multicast routing.
<SwitchA> system-view [SwitchA] multicast routing [SwitchA-mrib] quit
# Enable IGMP on the receiver-side interface (VLAN-interface 100).
[SwitchA] interface vlan-interface 100 [SwitchA-Vlan-interface100] igmp enable [SwitchA-Vlan-interface100] quit
# Enable PIM-SM on VLAN-interface 101.

# Enable IP multicast routing, IGMP, and PIM-SM on Switch E and Switch I in the same way Switch A is configured. (Details not shown.)
# On Switch B, enable IP multicast routing, and enable PIM-SM on each interface.
