The register-source command specifies the source address used by the source's Designated router (DR) to send Register messages.
The undo register-source command restores the default setting.
| Parameter | Description | Value |
|---|---|---|
| interface-type interface-number | Specifies the type and number of the source's DR. | - |
By default, the source address used by the source's DR to send Register messages is not specified.
Usage Scenario
When the source IP address for sending Register messages is no longer the only IP address in the network for the Rendezvous Point (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
Before specifying the source IP address for sending Register messages, enable PIM-SM.
Configuration Impact
When you run the register-source command several times, the latest configuration overrides the previous ones.
Note
The command is effective only when the specified interface is in Up state.
