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. To view mapping between prefixes and SIDs in an IS-IS process, run the display isis segment-routing mapping-server command.

Example

The actual command output varies according to the device. The command output here is only an example.
