Thanks Pavlin and Kristian, for you input. My intention is trying to get BGP
up and play with loading it and see my CPU performance.

I found some interesting test scripts in the harness folder, which can serve
similar purpose.
May I know what is the way to write our own dump file for the router, since
i am not able to view icsi1.mrtd used in test_peering2.sh.
What is the content of icsi1.mrtd?

Also i found out that there is a function call on "get_ready_priority" under
xorp_bgp function consume the most CPU cycle. May i know what is the reason?
I counldn't get into the source code since it is showing assembly rather
then C.


Thanks.
Heng Juen.
