342 CHAPTER 18: MULTICAST PROTOCOL
■ 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 323.
Enabling PIM-SM
This configuration can be effective only after multicast is enabled.
Perform the following configuration in Interface view.
Repeat this configuration to enable PIM-SM on other interfaces. Only one multicast
routing protocol can be enabled on an interface at a time.
Once enabled PIM-SM on an interface, PIM-DM cannot be enabled on the same
interface and vice versa.
Configuring the PIM-SM Domain Border
After the PIM-SM domain border is configured, bootstrap messages cannot cross the
border in any direction. In this way, the PIM-SM domain can be split.
Perform the following configuration in Interface view.
By default, no domain border is set. After this configuration is performed, a bootstrap
message cannot cross the border but other PIM packets can. This configuration can
effectively divide a network into domains using different BSRs.
Entering the PIM View
Global parameters of PIM should be configured in PIM view.
Perform the following configuration in system view.
Using
undo pim command, you can clear the configuration in PIM view, and back to
system view.
