Hi Yali, 

Speaking as WG member:

So this rather simplistic draft can be summarized as separate out the non-routing info into different LSPs, tag the corresponding LSPs, and then implementations can "do the right thing". As we already have RFC 8202 which offers clean separation, I don't know why we'd consider this under specified proposal. 

Using a separate instance offers other advantages such only requiring those IS-IS routers that need the non-routing information to be in the topology and providing a separate LSPs space for the new instances.

Speaking as WG Co-chair:

Given the feedback you've received thus far, do you still want to present this draft at IETF 110?

Thanks,
Acee

    Hi all,

    In order to separate multiple flooding instances for dissemination of routing information and other types of application-specific information to minimizes the impact of non-routing information flooding on the routing convergence and stability, We submitted a new IS-IS flooding mechanism implemented in the zero IS-IS instance, named as IS-IS Multi-flooding Instances (MFIs).

     An encoding format for IS-IS MFI-ID TLV and MFIs Update Process defined in this draft could be found in https://datatracker.ietf.org/doc/draft-wang-lsr-isis-mfi/ .

    Any questions and comments are welcome.

    Thanks,
    Yali

    Abstract:
       This document proposes a new IS-IS flooding mechanism which separates
       multiple flooding instances for dissemination of routing information
       and other types of application-specific information to minimizes the
       impact of non-routing information flooding on the routing convergence
       and stability.  Due to different flooding information has different
       requirements on the flooding rate, these multi-flooding instances
       should be given various priorities and flooding parameters.  An
       encoding format for IS-IS Multi-Flooding Instance Identifier (MFI-ID)
       TLV and Update Process are specified in this document.

    Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
