register-source (IPv6)

Function

The register-source command specifies an IPv6 address using which the source's designated router (DR) sends Register messages.

The undo register-source command restores the default setting.

By default, no IPv6 address is specified for the source's DR to send Register messages.

Usage Guidelines

Usage Scenario

If the source's DR uses more than one or a filtered out IPv6 address to send Register messages to the rendezvous point (RP), errors occur in the registration process and extra traffic occupies bandwidth on the network. To address this issue, run the register-source command to specify an IPv6 unicast address (a loopback interface's address is recommended) using which the source's DR sends Register messages.

Prerequisites

PIM-SM has been enabled on the interface of the IPv6 address to be specified by the ipv6-address parameter.

Configuration Impact

If the register-source command is run more than once, the latest configuration overrides the previous one.

Precautions

The command configuration is effective only when the interface of the specified IPv6 address is in the Up state.

Example

# In the public network instance view, specify 2001:DB8:11::1 as the IPv6 address using which the source's DR sends Register message.
