Working on this. Try to figure out how to carry key name in PCED sub-TLV. It looks RFC5088 and RFC5089 doesn't allow add additional sub-TLVs. " RFC5088 No additional sub-TLVs will be added to the PCED TLV in the future. If a future application requires the advertisement of additional PCE information in OSPF, this will not be carried in the Router Information LSA.
RFC5089 No additional sub-TLVs will be added to the PCED TLV in the future. If a future application requires the advertisement of additional PCE information in IS-IS, this will not be carried in the CAPABILITY TLV. " The reason behind was clarified here: https://mailarchive.ietf.org/arch/msg/pce/cR7e1SZ_DyUyY14OkfWbCc94paU I am wondering whether there is any other key information exchange that might be happening during discovery mechanism. Depending on the answer, we have three options: 1) Update RFC5088 and RFC 5089 to allow additional sub-TLVs to be added to the PCEP TLV. 2) carry key name using GENINFO TLV of RFC 6823 3) Carry key name during PCEP session establishment phase instead of discovery phase. -Qin -----邮件原件----- 发件人: Lsr [mailto:lsr-boun...@ietf.org] 代表 Acee Lindem (acee) 发送时间: 2018年11月15日 23:18 收件人: julien.meu...@orange.com; l...@ietf.org 抄送: pce@ietf.org 主题: Re: [Lsr] WG Adoption Poll for IGP extension for PCEP security capability support in the PCE discovery - draft-wu-lsr-pce-discovery-security-support-00 Authors, Please note that you need not wait until the end of the adoption poll to address my comment and Julien's comments.
