Configure OSPF on the switches in the PIM-SM domain to ensure network-layer reachability among them.
(Details not shown)
2.
Enable IP multicast routing, and enable PIM-SM and IGMP.
# Enable IP multicast routing on Switch A, enable PIM-SM on each interface, and enable IGMP on
VLAN-interface 100, which connects Switch A to the stub network.
<SwitchA> system-view
[SwitchA] multicast routing-enable
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] igmp enable
[SwitchA-Vlan-interface100] pim sm
[SwitchA-Vlan-interface100] quit
[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
The configuration on Switch B and Switch C is similar to that on Switch A. The configuration on Switch D
and Switch E is also similar to that on Switch A except that it is not necessary to enable IGMP on the
corresponding interfaces on these two switches.
3.
Configure a C-BSR and a C-RP.
# On Switch D, configure the service scope of RP, specify 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> 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
[SwitchD] pim
[SwitchD-pim] c-bsr vlan-interface 105 32 10
[SwitchD-pim] c-rp vlan-interface 105 group-policy 2005
[SwitchD-pim] quit
# On Switch E, configure the service scope of RP advertisements, specify 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> 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
[SwitchE] pim
[SwitchE-pim] c-bsr vlan-interface 102 32 20
[SwitchE-pim] c-rp vlan-interface 102 group-policy 2005
[SwitchE-pim] quit
4.
Verify the configuration.
Carry out the display pim interface command to view the PIM configuration and running status on each
interface. For example:
# View the PIM configuration information on Switch A.
[SwitchA] display pim interface
