The article in fact is about techniques to minimize the memory consumption of a BGP implementation. However, the table on the "Conclusion" section answers my question:
Well, if this table is true, I can easily tell a BGP table with 100,000 entries would takes around 70 Megabytes.
One of my friends confirms it is a good estimation on his BGP router. Is this estimation also working for you? Please share with me!
