Usage Guidelines

Usage Scenario

All C-RPs in a PIM-SM domain periodically send Advertisement messages to the same BSR. The BSR can collect the integrated RP-Set.

The c-rp advertisement-interval command sets the interval at which a C-RP sends Advertisement messages to the BSR.

Prerequisites

IP multicast routing has been enabled using the multicast routing-enable command.

Precautions

You can also set the advertisement interval when you run the c-rp interface-type interface-number advertisement-interval adv-interval command in the PIM view to configure the C-RP interface. The c-rp advertisement-interval interval command specifies the global advertisement interval. If both the commands are configured, the interval configured by the c-rp interface-type interface-number advertisement-interval adv-interval command takes effect.

Example

# In the PIM view of public network instance, set the interval at which a C-RP sends Advertisement messages to 30s.
