Hello,
I noticed in BGPlay the same reannouce event continuously repeats itself every 30s. Is this an expected behavior?
Yes, it happens sometimes that prefixes are announced multiple times or periodically. What you see there is just what our route collectors received. For this reason there is the option “ignore re-announcements” in the query panel (click the wrench). All the periodic announcements not introducing or changing anything in the scene will be filtered.
