The problem with metro-based addressing is that the statement above is equally true for it as for PA addressing.
Understanding the truth in that general statement, I would like to know if anyone sees a significant difference in the number of holes created by each approach. Handwaving can go either way, so the question is given real topologies and multi-homing goals, is there enough difference in the number of holes created to bias the approach?
