SO now going back to your analysis of the pt-pt link case. I think you may have misunderstood how the reverse SPF is used. Remember that it is ONLY the portion of the RSPF which crosses the link under consideration which is interesting.
If I understand this correctly, what you are saying is that you do an RSPF for each end of the link and take the results from the one whose first hop is across the link which just failed. This is how you resolve the multiple RSPFs required for a single link failure.
If multiple link failures are reported in the same LSP/LSA, then how do you decide which of the RSPFs to use? Do you take the maximum hopCount of all RSPFs which go across a failed link?
If additional link failures are reported in a different LSP/LSA, then how do you decide which of the RSPFs to use (among the one selected for this LSP/LSA and the current one)?
