• Determine the BS period. • Determine the BS timeout. • Determine the ACL rule for register message filtering. • Determine the register suppression time. • Determine the register probe time. • Determine the ACL rule and sequencing rule for disabling the switchover to SPT. Enabling PIM-SM With PIM-SM enabled, a router sends hello messages periodically to discover PIM neighbors and processes messages from the PIM neighbors. To deploy a PIM-SM domain, enable PIM-SM on all non-border interfaces of the routers. IMPORTANT: All the interfaces on the same router must operate in the same PIM mode. Step 1. Enter system view. 2. Enable IP multicast routing. 3. Enter interface view. 4. Enable PIM-SM. Command system-view multicast routing-enable interface interface-type interface-number pim sm Remarks N/A Disabled by default N/A Disabled by default For more information about the multicast routing-enable command, see IP Multicast Command Reference. Configuring an RP An RP can be manually configured or dynamically elected through the BSR mechanism. For a large PIM network, static RP configuration is a tedious job. Generally, static RP configuration is just a backup method for the dynamic RP election mechanism to enhance the robustness and operational manageability of a multicast network. Configuring a static RP If only one dynamic RP exists in a network, manually configuring a static RP can avoid communication interruption because of single-point failures. It can also avoid frequent message exchange between C-RPs and the BSR. To enable a static RP to work normally, perform this configuration on all the routers in the PIM-SM domain and specify the same RP address. To configure a static RP: Step 1. Enter system view. 2. Enter PIM view. Command system-view pim Remarks N/A N/A 118

Configuring an RP
An RP can be manually configured or dynamically elected through the BSR mechanism. For a large PIM
network, static RP configuration is a tedious job. Generally, static RP configuration is just a backup
method for the dynamic RP election mechanism to enhance the robustness and operational
manageability of a multicast network.
Configuring a static RP
If only one dynamic RP exists in a network, manually configuring a static RP can avoid communication
interruption because of single-point failures. It can also avoid frequent message exchange between C-RPs
and the BSR.
