Hi Tony,
while I appreciate the flexibility associated with the centralized
computation of the flooding topology, it has some drawbacks as well:
1. "flooding topology" must be flooded. This makes the flooding
dependent on the flooded data itself.
2. The extra flooding of "flooding topology" adds some delay in the
convergence towards the new "flooding topology".
Have you considered the distributed computation of "flooding topology"
using some standardized algorithm?
Eventually we can support multiple standardized algorithms. A node can
advertise support for several algorithms and the "active" algorithm is
selected based on some criteria that would guarantee that all nodes in
the flooding domain select the same one.
thanks,
Peter

Hi all,
I’ve submitted an updated version of my draft. Several changes:
- This collapses the two documents into one, so IS-IS is now included.
Placeholders are there for OSPF.
- I’ve expanded the discussion of failure modes.
- Minor bug fixes.
Your comments are solicited…
Tony

Abstract:
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.
Please note that it may take a couple of minutes from the time of
submission
until the htmlized version and diff are available at tools.ietf.org
