Usage Guidelines

Usage Scenario

When the source IPv6 address for sending Register messages is no longer the only IPv6 address in the network for the RP device or the source IPv6 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 IPv6 address for sending Register messages. Using the loopback address of the source's DR as the source IPv6 address is recommended.

Prerequisites

IPv6 multicast routing has been enabled globally using the multicast ipv6 routing-enable command in the system view.

Before specifying the source IPv6 unicast address for sending Register messages, enable PIM-SM.

Precautions

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

Example

# Specify the source IPv6 address used by the source's DR to send Register message as FC00:0:0:1101::1.
