Release Information

Statement introduced in Junos OS Release 15.1 F4 and 16.2R1 for the MX Series and PTX Series.


Enable purge originator identification (POI) by adding the type, length and value (TLV) with the Intermediate System (IS) identification to the LSPs that do not contain POI information. If an IS generates a purge, Junos adds this TLV with the system ID of the IS to the purge.

If an IS receives a purge that does not include this TLV, it adds this TLV with both its own system ID and the system ID of the IS from which it received the purge. This allows the IS that receives this purge to log the system ID of the originator, or the upstream source of the purge and makes it easier to locate the origin of the purge.


empty(Optional) Add POI to a purge received from an IS that does not contain POI information
self(Optional) Add POI only to self-originated purge LSPs
