UPDATE Packing
If your BGP tables contains 100k routes and 15k attribute combinations then you can advertise all the routes with 15k updates if you pack the prefixes 100%
If it takes you 100k updates then you are achieving 0% update packing
Convergence times vary greatly depending on the # of attribute combinations used in the table and on how well BGP packs updates
