Configuring PIM-SM
This section describes how to configure PIM-SM.
PIM-SM configuration task list
(Required.) Enabling PIM-SM N/A
(Required.) Configuring an RP:
• Configuring a static RP
• Configuring a C-RP
• (Optional.) Enabling Auto-RP listening
• (Optional.) Configuring Anycast RP
You must configure a static RP, a
C-RP, or both in a PIM-SM
domain.
Configuring a BSR:
• (Required.) Configuring a C-BSR
• (Optional.) Configuring a PIM domain border
• (Optional.) Disabling BSM semantic fragmentation
• (Optional.) Disabling BSM forwarding out of incoming interfaces
Skip the task of configuring a BSR
on a network without C-RPs.
(Optional.) Configuring multicast source registration N/A
(Optional.) Configuring the switchover to SPT N/A
(Optional.) Configuring common PIM features N/A
Configuration prerequisites
Before you configure PIM-SM, configure a unicast routing protocol so that all devices in the domain
can interoperate at the network layer.
Enabling PIM-SM
Enable IP multicast routing before you configure PIM.
With PIM-SM enabled on interfaces, routers can establish PIM neighbor relationship and process
PIM messages from their PIM neighbors. As a best practice, enable PIM-SM on all non-border
interfaces of routers when you deploy a PIM-SM domain.
IMPORTANT:
All the interfaces on the same router must operate in the same PIM mode in the public network or
To enable PIM-SM:
1. Enter system view.
