Hi, All: We have submitted the update version about "Prefix Unreachable Announcement" draft, which contains signification simplification for its contents and the clarification of some key points of the mechanism, based on the discussion on the list and off the list with LSR experts. We will try to make some summarizations on the coming IETF meetings. Please feel free to comments on the updated contents, or the overall solution.

It is mainly used in the scenarios that the summary prefixes are advertised at the border routers whereas the services endpoints are located in different IGP areas or levels, whose reachabilities are covered by the summary prefixes. It introduces a new signaling mechanism using a negative prefix announcement called Prefix Unreachable Announcement Mechanism(PUAM), utilized to detect a link or node down event and signal the overlay services that the event has occurred to force immediate switchover.
