encapsulates the C-RP information and its own IP address in a BSM, and floods the BSM to all PIM
routers in the domain.
An advertisement message contains a holdtime option, which defines the C-RP lifetime for the
advertising C-RP. After the BSR receives an advertisement message from a C-RP, it starts a timer for
the C-RP. If the BSR does not receive any advertisement message when the timer expires, it
considers the C-RP failed or unreachable.
To configure a C-RP:
Step
Enter system view.
1.
Enter PIM view.
2.
Configure a C-RP to provide
3.
services for BIDIR-PIM.
Enabling Auto-RP listening
This feature enables the device to receive Auto-RP announcement and discovery messages and
learn RP information. The destination IP addresses for Auto-RP announcement and discovery
messages are 224.0.1.39 and 224.0.1.40, respectively.
To enable Auto-RP listening:
Step
Enter system view.
1.
Enter PIM view.
2.
Enable Auto-RP listening.
3.
Setting the maximum number of BIDIR-PIM RPs
In a BIDIR-PIM domain, one DF election per RP is implemented on all PIM-enabled interfaces. As a
best practice to avoid unnecessary DF elections, do not configure multiple BIDIR-PIM RPs.
This configuration sets a limit on the number of BIDIR-PIM RPs. If the number of RPs exceeds the
limit, excess RPs do not take effect and can be used only for DF election rather than multicast data
forwarding. The system does not delete the excess RPs. They must be deleted manually.
To set the maximum number of BIDIR-PIM RPs:
Step
Enter system view.
1.
Enter PIM view.
2.
Set the maximum number of
3.
BIDIR-PIM RPs.
