[Click] Re: click Digest, Vol 29, Issue 17

Hi,

I wanted to measure the performance of IP lookup for Lulea trees and other 
kinds of look up.
I see some measurement figures in
http://pdos.csail.mit.edu/click/doc/IPRouteTable.n.html

How do I go about it?

Here is my idea about..I can send packets hard coded but then how do I make 
entries in routing table?

Any pointer in this regard would be a great help.

Thanks,
Siddharth
