Alan,
You are correctly concerned about flooding, however, I suspect that you're
underestimating the scalability problems of flooding. Please recall that
it's O(n^2) in the number of nodes in your mesh. This is a serious threat
to building very large domains. In addition, the full mesh prevents
hierarchical abstraction within the domain, defeating the other obvious
mechanism for IGP scalability.
