Re: [netmod] [Lsr] I-D Action: draft-ietf-lsr-ospfv3-extended-lsa-yang-10.txt

In the MIB,  the base types don't include the zone - https://www.ietf.org/rfc/rfc4001.txt

It was very unfortunate that the YANG IP addresses included the zone in the base types. 

Tom - I think it would be hard to find an author where including the zone was a conscious decision. 

Thanks,

    Hi Tom, +Juergen, netmod WG,

    I think the question you ought to be asking is whether the base IPv4 and IPv6 address types should be modified to NOT include the zone and the zone versions should be added as a separate YANG type.

    The RFC 6991 is under revision now:

    https://datatracker.ietf.org/doc/draft-ietf-netmod-rfc6991-bis/

    However, I'm not sure if the painful backward compatibility discussions could be overcome.  We'd also have to admit that it was a big mistake to include the zone in the base addresses. In any case, I don't think we just start using the no-zone types when the base addresses types are used everywhere.

    <tp>

    Well, there are plenty of uses of the no-zone types as well, so some authors, some YANG doctors, have made the conscious choice to use them.  I cannot do a search just now but I see no-zone in the dhc and I2NSF WG I-Ds, and there are others.

    Also, some authors want the zone information as part of their leaf.

    Thanks,
    Acee

        I assume that this is a refresh while waiting for ospf.yang to wind its way through the system

        I wonder if the ip address should be the no-zone variant from RFC6991 - I never know the answer to that so keep asking.

        Some time the contact needs updating to https://datatracker and the TLP to 'Revised'

        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

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