(Required.) Enabling PIM-SM

(Required.) Configuring an RP

• Configuring a static RP

• Configuring a C-RP

NOTE:

Perform at least one of the above tasks.

In a network with a static RP, skip the task of configuring a BSR.

Configuring a BSR:

• (Required.) Configuring a C-BSR

• (Optional.) Configuring a PIM domain border

• (Optional.) Disabling the BSM semantic fragmentation function

(Optional.) Configuring multicast source registration

(Optional.) Configuring switchover to SPT

(Optional.) Configuring common PIM features

Configuration prerequisites

Before you configure PIM-SM, configure a unicast routing protocol so that all devices in the domain are

interoperable 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. When you deploy a PIM-SM domain, HP recommends that you

enable PIM-SM on all non-border interfaces.

IMPORTANT:

ll the interfaces on the same router must operate in the same PIM mode in the public network or the same

PN instance.

To enable PIM-SM:
