I support WG adoption and have a few questions related to the draft.

Does this flooding algorithm use the dynamic flooding algorithm used in
data center clos dense meshed topologies with many ECMP paths where the
flood is decoupled from the physical topology.  In the dynamic flooding
algorithm mentioned in centralized mode the flooding is computed by the
area leader and distributed to all nodes.  In distributed mode each mode
the area leader determines the algorithm and then each node computes the
flooding topology based on the algorithm.

This dynamic algorithm for optimized flood reduction would reduce the
amount of redundant flooding in highly densely meshed ospf or Isis
topologies.  So this optimization of flooding would improving overall link
state routing protocol convergence.
