Hi, LSR experts: We have uploaded the new version of this PUA(Prefix Unreachable Announcement) draft. The main updates are the followings: 1) Describes the solution that using tunnel to redirect traffic among ABRs, when all ABRs reaches the PUA limit. 2) Describe fast rerouting to avoid routing black hole. 3) Defining PUA capabilities announcements for OSPFv2/OSPFv3 and ISIS.
There are also some arguments about the current solution for PUA, for example: 1) Is it suitable to set the "Prefix Originator" sub-TLV to NULL to indicate the prefix is unreachable? 2) if not, what's the consideration? What's the other convincible solution? Wish to hear comments and suggestions on the above issues. We will also have the presentation on the coming IETF LSR meeting.
