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.
where is this being 'detected?' i.e. from what vantage point? is it safe to assume that your outbound announcements to your two upstreams are stable? of course, if you would care to divulge a prefix showing this symptom, folk might be able to find clues. randy --- randy () psg com `gpg --locate-external-keys --auto-key-locate wkd randy () psg com` signatures are back, thanks to dmarc header butchery
