Usage Guidelines

Usage Scenario

All C-RPs in a PIM-SM domain send Advertisement messages to the same bootstrap router (BSR). An Advertisement message carries the C-RP address, range of multicast groups that the C-RP serves, and priority of the C-RP. In this manner, the BSR can collect complete RP-set information. To set an interval at which a C-RP sends an Advertisement message, run the c-rp advertisement-interval command.

Prerequisites

The multicast routing function has been enabled using the multicast routing-enable command in the public network instance view or VPN instance view.

Configuration Impact

If the c-rp advertisement-interval command is run more than once, the latest configuration overrides the previous one.

Example

# In the public network instance, specify 30 seconds as the interval at which a C-RP sends an Advertisement message.
