Patrice,
You "can't" understand why it did that? Did they bounce or all stay down? Did you clear neighbors and they came back up, or it solved it in time on its own? I am not sure I fully understand your question Regards, Tyson Scott - CCIE #13513 R&S, Security, and SP Managing Partner / Sr. Instructor - IPexpert, Inc.

I am wondering if you can give me possible reasons for that. The new neighbor (10.193.251.6) was added on a different SVI using PTP subnets, I can understand why I lost other neighbors and most routes were SIA.
