Parameters

Parameter	Description	Value
prefix-value	Specifies the IP prefix.	The value is in dotted decimal notation.
mask-len-value	Specifies the length of IP prefix.	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.
range range-value	Specifies the number of successive SIDs to be assigned.	The value is an integer ranging from 1 to 65535.

Usage Guidelines

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.

Example

# Configure mapping between two pairs of prefixes and SIDs. Assuming the SRGB range is 16000 to 23999, prefixes 10.1.1.1/32 and 10.1.1.2/32 are assigned SIDs 16010 and 16011, respectively.
