Release Information

Statement introduced in Junos OS Release 12.3.

Description

Specify the amount of time (in seconds) that a Path Computation Client (PCC) must wait before returning control of all LSPs to the routing protocol process after a PCEP session with the main active stateful Path Computation Element (PCE) is disconnected.

Note

In compliance with draft-ietf-pce-stateful-pce-09, revoking of PCE-initiated LSP delegations by a PCC happens in a make-before-break fashion before the LSPs are redelegated to an alternate PCE. Starting in Junos OS Release 18.1R1, the lsp-cleanup-timer must be greater than or equal to the delegation-cleanup-timeout for the PCC to revoke the LSP delegations. If not, the redelegation timeout interval for the PCC can be set to infinity, where the LSP delegations to that PCE remain intact until specific action is taken by the PCC to change the parameters set by the PCE.

Options

seconds—Time (in seconds) that a PCC must wait before returning control of all LSPs to the routing protocol process after a PCEP session with the main active stateful PCE is disconnected.

A value of 0 indicates immediate delegation cleanup.

Range: 0 through 2,147,483,647 seconds

Prior to Junos OS Release 18.4R1, the maximum range value is 600 seconds.

Default: 30 seconds
