Hi, Peter and Dirk: Thanks for your comments and the previous explanation. For the use case related to the topology retrieval, I have the following consideration, please point out if I have some misunderstandings for the OSPF LSA procedure: 1) For prefix that is rooted at only one router, such as the loopback address, only one originator for the prefix will be added by the ABR. 2) For prefix that is connected two nodes, such as the prefix that identifies the link between them, the originator information will be added twice for this prefix. Doing so does not the contradict with actual physical deployment. The originator information will be added by the ABR when it receives the Router LSA, as described in section 5 of the draft. When the ABR receives such information, it may not begin the SPF calculation and can't decide which side is closer to the ABR. Best Regards.
