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.
Table 350 Enabling PIM-SM
Operation
Enable PIM-SM on an interface
Disable PIM-SM on an interface
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.
Table 351 Configuring the PIM-SM domain border
Operation
Set the PIM-SM domain border
Remove the PIM-SM domain border
configured
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.
