Hi Yali,

    Dear authors,

    It's valuable work. After reading I have a clarifying question.

    As you defined a Container unknown-tlv and Grouping unknown-sub-tlv in each OSPFv3 Extended LSAs defined in [RFC8362], are these used for extension of new OSPF Extended LSAs and new attributes in each extended LSA, respectively?

Yes. 

    For example, if other attributes associated with Link are extended to E-Router-LSA TLV for access via NETCONF, does it can be directly augmented leaf of the List sub-tlvs in this YANG module? 

    If not, does it need to define a new YANG module used for other Link attributes can be accessed via NETCONF?

Yes. There are many features that utilize the OSPFv3 extended LSA format and these will correspond to new models. For example, OSPFv3 segment routing. 

Thanks,
Acee

    Best regards,
    Yali

    A New Internet-Draft is available from the on-line Internet-Drafts directories.
    This draft is a work item of the Link State Routing WG of the IETF.

            Title           : YANG Model for OSPFv3 Extended LSAs
            Authors         : Acee Lindem

    Abstract:
       This document defines a YANG data model augmenting the IETF OSPF YANG
       model to provide support for OSPFv3 Link State Advertisment (LSA)
       Extensibility as defined in RFC 8362.  OSPFv3 Extended LSAs provide
       extensible TLV-based LSAs for the base LSA types defined in RFC 5340.
