flap rate drop - 05/18/98 6Bone Routing Report (from Merit)



Someone must be doing something right to reduce the 6bone flap rate. Today's routing report for the 18th shows the least Announcement/Withdraw rate yet: 3861/150.

Least you think I exagerate, look at the reports for the last 8 days:

May 17-46135/22059 
May 16-153132/73394
May 15-154237/74892 
May 14-143464/69092 
May 13-97585/51533 
May 12-112330/61222 
May 11-77148/48238 
May 10-113953/92209 

And before this there were days in he millions of announcments!

Anyone know what's going on?  Or is this just the natual evolution of folks moving to more compatible BGP4+ versions?
