IS-IS purge originator identification TLV

Junos OS supports RFC 6232, Purge Originator Identification TLV for IS-IS, which defines a type, length and value (TLV) for identifying the origin of a purge initiated by the IS-IS protocol. You can configure this feature to add this TLV to a purge along with the system ID of the Intermediate System (IS) that has initiated this purge. This makes it easier to locate the origin of the purge and its cause.
