Usage Guidelines

Usage Scenario

When the source IP address for sending Register messages is no longer the only IP address in the network for the RP router or the source IP address is filtered out, errors occur in the registration process and extra traffic occupies bandwidth on the network. In this case, use the register-source command to specify an appropriate interface as the source IP address for sending Register messages. Using the loopback address of the source's DR as the source IP address is recommended.

Prerequisites

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

Before specifying the source IP address for sending Register messages, enable PIM-SM.

Precautions

The command is effective only when the specified interface is in Up state.

Example

# In the PIM view of public network instance, specify the IP address of loopback 0 as the source IP address for source's DR to send Register messages.
