Configure a candidate-RP
Remove the candidate-RP configured
When configuring RP, if the range of the served multicast group is not specified,
the RP will serve all multicast groups. Otherwise, the range of the served multicast
group is the multicast group in the specified range. It is suggested to configure
Candidate RP on the backbone router.
CAUTION: Using the group-policy command on a candidate RP, you can
configure only the permit rule After the configuration ofthe permit rule, the RP
only serves for groups included in the permit rule.
To enhance network robustness, static RP serves as the backup of dynamic RP
Table 459 Configure static RP
Operation
Enter system view
Enter PIM view
Configure static RP
CAUTION:
When the RP elected by BSR mechanism is effective, static RP does not work.
■
All routers in the PIM domain must be configured with this command
■
simultaneously, with the same RP address specified.
The system supports up to ten different static RP addresses. When more than
■
ten static RP addresses are configured, the system will give this prompt
information: "Cannot config static-rp, exceeded static-rp limit 10".
After the PIM-SM domain border is configured, bootstrap messages can not cross
the border in any direction. In this way, the PIM-SM domain can be split.
Perform the following configuration in interface view.
Table 460 Configure 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 can not cross the
border but other PIM packets can. This configuration can effectively divide a
network into domains using different BSRs.
