LSP Deletion Using PCEP

The following procedures apply in the deletion of a PCE-initiated LSP. More protocol level details are provided in RFC 8281. These procedures are applicable when the user manually deletes the PCE-initiated LSP or the NSP application, or when NSD requests the deletion of the PCE-initiated LSP. The procedures that apply when a network event occurs are described in SR OS Router Procedures.

The NSP crafts a PCInitiate message for the corresponding PLSP-ID and sets the R-bit in the SRP object flags to indicate to the PCC that it must delete the LSP. The NSP sends the message to the PCC using PCEP.
