The following errata report has been held for document update for RFC8231, "Path Computation Element Communication Protocol (PCEP) Extensions for Stateful PCE".
-------------------------------------- You may review the report below and at: https://www.rfc-editor.org/errata/eid5796 -------------------------------------- Status: Held for Document Update Type: Technical Reported by: Hillol <[email protected]> Date Reported: 2019-07-29 Held by: Deborah Brungard (IESG) Section: 7.3.3 Original Text ------------- Value Description ----- ------------------------------------- 1 Unknown reason 2 Limit reached for PCE-controlled LSPs 3 Too many pending LSP Update Requests 4 Unacceptable parameters 5 Internal error 6 LSP administratively brought down 7 LSP preempted 8 RSVP signaling error Corrected Text -------------- Remove Value 2 2 Limit reached for PCE-controlled LSPs Notes ----- Value 2 "Limit reached for PCE-controlled LSPs" can occur when an PC update message comes for either PCInitiated or PCDelegated LSP. But since the lsp is already created or delegated, it means the resource is available and allocated. Also RFC 8281 (section 5.3) states that if LSP provisioned exceeds the limit, an LSP error message should be sent with Error-type=19 (Invalid Operation) and Error-value=6 (PCE-initiated LSP limit reached). So, I believe there is no scenario where LSP Error code TLV "Limit reached for PCE-controlled LSPs" would be used. Please let me know if there is some scenario which can trigger the same. -------------------------------------- RFC8231 (draft-ietf-pce-stateful-pce-21) -------------------------------------- Title : Path Computation Element Communication Protocol (PCEP) Extensions for Stateful PCE Publication Date : September 2017 Author(s) : E.
