During the IETF 121 LSR meeting, we had a very good 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
