PIM-SM non-scoped zone configuration example

Network requirements

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 PIM-SM domain contains only one BSR.
Host A and Host C are multicast receivers in two stub networks N1 and N2.
Both VLAN-interface 105 on Switch D and VLAN-interface 102 on Switch E act as C-BSRs and C-RPs. The C-BSR on Switch E has a higher priority. The C-RPs are designated to the multicast group range 225.1.1.0/24. Modify the hash mask length to map the multicast group range to the two C-RPs.
IGMPv2 runs between Switch A and N1, and between Switch B, Switch C, and N2.

Configuration procedure

Assign an IP address and subnet mask to each interface according to Figure 33. (Details not shown.)
Enable OSPF on all switches on the PIM-SM network to make sure the following conditions are met: (Details not shown.)
- The switches are interoperable at the network layer.
- The switches can dynamically update their routing information.
Enable IP multicast routing, and enable IGMP and PIM-SM:
# On Switch A, enable IP multicast routing globally.
```
<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-DM on the other interfaces.
```
[SwitchA] interface vlan-interface 101
[SwitchA-Vlan-interface101] pim sm
[SwitchA-Vlan-interface101] quit
[SwitchA] interface vlan-interface 102
[SwitchA-Vlan-interface102] pim sm
[SwitchA-Vlan-interface102] quit
```
# Enable IP multicast routing, IGMP, and PIM-SM on Switch B and Switch C in the same way Switch A is configured. (Details not shown.)
# Enable IP multicast routing and PIM-SM on Switch D and Switch E in the same way Switch A is configured. (Details not shown.)

Configure C-BSRs and C-RPs:

# On Switch D, configure the service scope of RP advertisements.

<SwitchD> system-view
[SwitchD] acl number 2005
[SwitchD-acl-basic-2005] rule permit source 225.1.1.0 0.0.0.255
[SwitchD-acl-basic-2005] quit

# Configure VLAN-interface 105 as a C-BSR and a C-RP, and set the hash mask length to 32 and the priority of the C-BSR to 10.

[SwitchD] pim
[SwitchD-pim] c-bsr 192.168.4.2 hash-length 32 priority 10
[SwitchD-pim] c-rp 192.168.4.2 group-policy 2005
[SwitchD-pim] quit

# On Switch E, configure the service scope of RP advertisements.

<SwitchE> system-view
[SwitchE] acl number 2005
[SwitchE-acl-basic-2005] rule permit source 225.1.1.0 0.0.0.255
[SwitchE-acl-basic-2005] quit

# Configure VLAN-interface 102 as a C-BSR and a C-RP, and set the hash mask length to 32 and the priority of the C-BSR to 20.

[SwitchE] pim
[SwitchE-pim] c-bsr 192.168.9.2 hash-length 32 priority 20
[SwitchE-pim] c-rp 192.168.9.2 group-policy 2005
[SwitchE-pim] quit
