I agree with Rob & Tony. Converging on single algorithm across zoo of vendors is not going to happen bearing in mind that every single change to such algorithm will require a massive 1000s nodes software upgrade each time. Note that even if IETF converges industry may not and that is a practical

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 > Begin
