The mapping-server prefix-sid-mapping command configures mapping between a specific or multiple pairs of prefixes and SIDs.
The undo mapping-server prefix-sid-mapping command deletes mapping between a specific or multiple pairs of prefixes and SIDs.
By default, no mapping between prefixes and SIDs is configured.
| Parameter | Description | Value |

| prefix-value |
Specifies the IP prefix. |
The value is in dotted decimal notation. |
| mask-len-value |

The value is an integer ranging from 0 to 32.Only the 32-bit mask length is supported currently. |
| sid-value |
Specifies the start of SID index range. |
The value is an integer ranging from 0 to 65534. |

Usage Scenario
In LDP and SR interworking scenarios, if SR is not supported on the LDP side, run the mapping-server prefix-sid-mapping command on an SR device to map the LDP prefixes to SIDs and advertise the mapping to the SR domain. This command is run on a mapping server.
Precautions
The Mapping SID is assigned to the IP address prefix with 32-bit mask only.
