          1) Agenda (Loa):
          
          Misref (draft-ietf-mpls-spring-entropy-label) document:
              Adrian:     Waiting on the base SR draft.
                              That completed LC and waiting for the sheppard
                              write-up to move forward
          
          
          2)        draft-nslag-mpls-deprecate-md5        4        11:36:00
          11:44:00        8        Andrew Malis        Y
          
          Rajiv Asati:
              aware of 10 (at least) network that use LDP with MD5
              Would they care to replace MD5 with AO - not sure probably no
              Maybe draft would have clear recommendation on what to use
          
              Adrian :
                  use of MD5 as security
                  MD5 is not secure to be called security
                  Nothing happened so far - so why care, is this enough to call
                  it secure?
          
          
          Loa:
              MD5 is there in networks
              do they know/care if it is secure enough
              what are the threats and are they addressed by MD5, by AO?
          
          Deborah:
              agree with Adrian.
              It is important to discuss this
          
          3)        draft-andersson-mpls-spl-terminology        1        11:45:00
          11:55:00        10        Adrian Farrel        Y
          
          Julien Muric:
              Does it mean we can have ebSPL?
          
          4)        draft-hu-mpls-sr-inter-domain-use-cases        1        11:56:00
          12:06:00        10        Quan        Y
          
          Loa:
              SPRING charter says that it works within 1 trust domain (with some
              exception)
              The work presented is for cross-domains, -> Deborah should charter
              for SPRING change
              May need some discussion on trust domains
              assumption can be made that SR domain and MPLS-TP domain
          
          Deborah:
              with care of the word "domain" what it means
              Work with the chairs of SR and this is still an early document
              suggest to cc the SR list to engage/feedback
          
          {...}/Juniper:
              what do you mean by domain? IGP area? AS? technoliogy domain?
          
          Charle Halpern
                  To interwork between SR-MPLS and MPLS-TP
                  Suggest to drop the inter-domain argument to simplify the
                  discussion
          
          Greg Mirstky:
              clarify how the name is used in the context of this proposal (as
              Debora said)
              Suggest aligning with interpretation with SR-MPLS terminolgy
              We'll need to clarify mapping of SR-domain and this usecase
          
          Adrian:
              SPRING used "SR domain" as a trust domain
          
          5)        draft-zheng-mpls-lsp-ping-yang-cfg        10        12:07:00
          12:22:00        15        Greg MIRSKY        Y
          Loa:
              Started a WGAP, but found issues.
              Closed WGAP and asked Greg to work with reviewers to address comments
              and will restart the WGAP later
          
          Tarek/Nagendra: the RSVP IPv4 LSP FEC and IPv6 LSP FEC is defined and
          used in OAM
          
          6)        draft-nainar-mpls-rfc8287-len-clarification        0
          12:23:00        12:33:00        10        Nagendra Kumar        Y
          
          Loa: procedural. You need to send a request for WGAP (for book keepoing)
          
          7)        draft-chen-mpls-cqf-lsp-dp        0        12:34:00
          12:42:00        8        Zhe Chen        Y
          
          Rajiv:
              how upstream router learns ...
          
          Greg:
              For DETNET - even for local behavior -- document is useful to clarify
              xx
          
          Title mention CQF (IEEE) and then large-scale
          A: this draft target large scale and LDN .. maybe terms are not correct
          
          Loa:
              there are some questions that we're asking clarification, so lets
              use the list to clarify
          
          8)        draft-cheng-mpls-inband-pm-encapsulation        0
          12:43:00        12:51:00        8        Xiao Min        Y
          Qs: none
          Loa: authors need to push the discussion on the list
          
          9)        draft-kumar-mpls-mint        0        12:51:00        13:01:00
          10        Jai Kumar        Y
          Greg:
              We had the discussion when original proposal when iOAM and this may
              be misleading
              Active OAM can be in-band
              In MPLS, with EL then they are in-band
              in-band: follow same nodes/links
          A: open to changes in the name of the draft
          
          Greg:
              2 or 3 proposals in IPPM - not dataplane specific
              on-path telemetry collection
              instead of using label - why not use GACH type
          A:GAch: was considered but there was issues - will add to appendix
              Have you looked at the applicability of this to SR-MPLS
              May have multiple insertions due to
          
          Adrian:
              Please take out the IANA allocated value and add TBD
          
          Nagendra:
              what happen on the egress
              A: there are 2 ways to handle it - may be ok for flexible NPU
          
          Greg:
              I strongly encourge to read the other propsals
          
          Loa: expect authors to pushing discussion on the list
