Supports for the adoption of two drafts at the same time, IGP Reduce Flooding still have some problem needs to be solved, for example, how to ensure the reliability of Flooding in a multi-point failure scenario. The way to solve these problems in a distributed and centralized manner may be different. Therefore, it is recommended to promote separately and continue to conduct research in their respective directions.

Hi, Christian: Supports for the adoption of two drafts at the same time, in which one(draft-li-lsr-dynamic-flooding-02) focuses on the centralized mode and the other(draft-cc-lsr-flooding-reduction-01) focuses on the distributed mode. The centralized mode for is one straightforward way to realize the flooding reduction, and I admire Tony Li give his solution first. But from the consideration of solution robustness, the distributed mode may be more promising. My consideration for distributed mode is that it should not cover only the algorithm, more contents need to be standardized in future. Huaimo has one good start point for distributed mode, and he also gives abundant thoughts for the centralized mode that the current version of draft-li-lsr-dynamic-flooding-02 has not covered yet. Proposal for the name of two drafts may be draft-ietf-lsr-flooding-reduction-centralized-mode and draft-ietf-lsr-flooding-reduction-distributed-mode. Best Regards.

Hi Folks, We are starting a 2 week adoption call on draft-li-lsr-dynamic-flooding-02. The aim of this document is to describe the problem space and standardize a way to signal dynamic flooding information. It does not standardize any specific algorithm for flooding topology creation. Authors please respond indicating if you are aware of any IPR related to this work. We also have another draft (draft-cc-lsr-flooding-reduction-01) that started as a distributed flooding topology algorithm and morphed into that plus competing ideas on signaling of flooding topology information. The intent after adoption of draft-li-lsr-dynamic-flooding-02 is two-fold. One, the WG can discuss adding any signaling ideas from this work to the adopted signaling draft (with proper attribution given as appropriate), and two, for the authors of draft-cc-lsr-flooding-reduction-01 to publish a new document without the signaling portion and instead focus on their flooding topology algorithm. This new focused document can be considered in parallel along with the other algorithm work that has been proposed. Flooding topology creation is seen as a hard problem for which we don't expect a one-size-fits-all solution. Taking the steps outlined above will help us move forward on the solutions. Thanks, Chris & Acee.
