Dear Guru(s), My apologies upfront if this question has already been asked. If that’s the case, please kindly point me to the solution|thread so that the mailing list bandwidth is not wasted. Situation: On one of our prefixes, we are detecting continuous “BGP AS-Path Changes” in the order of 1,000 announcements per hour---practically one every 3-4 seconds. Those paths oscillate between two of our immediate upstreams. Questions: 1. Is this number of events “normal” for a prefix? 2. Is there any way we, as the tail-end (Origin Announcer), can do to reduce it? Or should I just “let it be”? 3. [Extra] Is this kind of oscillation affecting user experience, say, throughput and/or latency? Thank you in advance for all the pointers and help. Best Regards, Pirawat.
