IGP Extension for Path Computation Element Communication Protocol (PCEP) Security Capability Support in PCE Discovery (PCED)
RFC 9353

Received changes through RFC Editor sync (created alias RFC 9353, changed title to 'IGP Extension for Path Computation Element Communication Protocol (PCEP) Security Capability Support in PCE Discovery (PCED)', changed abstract to 'When a Path Computation Element (PCE) is a Label Switching Router (LSR) or a server participating in the Interior Gateway Protocol (IGP), its presence and path computation capabilities can be advertised using IGP flooding. The IGP extensions for PCE Discovery (PCED) (RFCs 5088 and 5089) define a method to advertise path computation capabilities using IGP flooding for OSPF and IS-IS, respectively. However, these specifications lack a method to advertise Path Computation Element Communication Protocol (PCEP) security (e.g., Transport Layer Security (TLS) and TCP Authentication Option (TCP-AO)) support capability.

This document defines capability flag bits for the PCE-CAP-FLAGS sub-TLV that can be announced as an attribute in the IGP advertisement to distribute PCEP security support information. In addition, this document updates RFCs 5088 and 5089 to allow advertisement of a Key ID or KEY-CHAIN-NAME sub-TLV to support TCP-AO security capability. This document also updates RFCs 8231 and 8306.', changed pages to 13, changed standardization level to Proposed Standard, changed state to RFC, added RFC published event at 2023-01-13, changed IESG state to RFC Published, created updates relation between draft-ietf-lsr-pce-discovery-security-support and RFC 5088, created updates relation between draft-ietf-lsr-pce-discovery-security-support and RFC 5089, created updates relation between draft-ietf-lsr-pce-discovery-security-support and RFC 8231, created updates relation between draft-ietf-lsr-pce-discovery-security-support and RFC 8306)
