196 CHAPTER 7: MULTICAST PROTOCOL
Configuring Static RP
The router that serves as the RP is the core router of multicast routes. If the
dynamic RP elected by BSR mechanism is invalid for some reason, the static RP can
be configured to specify RP. As the backup of dynamic RP, static RP improves
network resilience and enhances the operation and management capability of
multicast network.
Configuring PIM-SM PIM-SM basic configuration includes:
■ Enabling Multicast
■ Enabling PIM-SM
■ Configuring the PIM-SM Domain Border
■ Entering the PIM View
■ Configuring Candidate-BSRs
■ Configuring Candidate-RPs
■ Configuring Static RP
PIM-SM advanced configuration includes:
■ Configuring the Sending Interval for the Hello Packets of the Interface
■ Configuring the Filtering of Multicast Source/Group
■ Configuring the Filtering of PIM Neighbor
■ Configuring the Maximum Number of PIM Neighbor on an Interface
■ Configuring RP to Filter the Register Messages Sent by DR
■ Limiting the Range of Legal BSR
■ Limiting the Range of Legal C-RP
■ Clearing Multicast Route Entries from PIM Routing Table
■ Clearing PIM Neighbors
It should be noted that at least one router in an entire PIM-SM domain should be
configured with Candidate-RPs and Candidate-BSRs.
Enabling Multicast
Refer to “Common Multicast Configuration” on page 177.
Enabling PIM-SM
This configuration can be effective only after multicast is enabled.
Perform the following configuration in Interface view.
