Hi authors:

    Regarding this Draft, I have always had a question, how does dynamic 
flooding ensure the reliability of Flooding under multiple points of failure. 
Flooding depends on the consistent LSDB / Flooding SPF tree across the entire 
network, and the consistent LSDB on the entire network depends on Flooding. 
There will be different nodes with different LSDBs. In this case, how to ensure 
the reliability of Dynamic flooding? IETF 106 meeting says that products have 
been implemented for Dynamic Flooding. Has the reliability of Dynamic Flooding 
been tested in multi-point failure scenarios?

Thank you

   Routing with link state protocols in dense network topologies can
   result in sub-optimal convergence times due to the overhead
   associated with flooding.  This can be addressed by decreasing the
   flooding topology so that it is less dense.

   This document discusses the problem in some depth and an
   architectural solution.  Specific protocol changes for IS-IS, OSPFv2,
   and OSPFv3 are described in this document.
