Hi Acee,

I firmly believe it’s worthwhile to work on an additional mechanism for 
distributed flooding reduction, which is easier to deploy and has a minimal 
blast radius.

Best regards,
Xiaohu

主题: [Lsr] Consensus Call on LSR WG work on "Leaderless Flooding Algorithm for 
Distributed Flood Reduction to allow reduced configuration, minimal blast 
radius, and ease of incremental deployment"

During the IETF 121 LSR meeting, we had an excellent discussion of 
https://datatracker.ietf.org/doc/draft-ietf-lsr-distoptflood/

While the CDS flooding reduction algorithm itself was interesting, the main 
area of the discussion was distributed flooding reduction algorithm selection 
and its configuration and deployment.

Today, we have RFC 9667 “Dynamic Flooding on Dense Graphs” which provides 
leader-based supporting both centralized and distributed flooding reduction 
algorithm selection. With the mechanism, an area leader is selected from among 
the OSPF routers in the area supporting flooding reduction and this leader 
selects the flooding reduction algorithm for the area.

The question to be answered by this consensus call is whether or not we want to 
work on an additional mechanism just for distributed flooding reduction to 
allow for reduced configuration, minimal blast radius, and ease of incremental 
deployment.

Please send your support or opposition to this list before Tuesday, December 
3rd.

As WG Co-Chair,
Acee
