Thank you very much for your response Murphy,
I have decided to use pox carp branch and running it with the
brandonheller(git://github.com/brandonheller/ripl.git, git://
github.com/brandonheller/riplpox.git) version of ripL and ripLpox but
getting following error on pox controller:
Traceback (most recent call last):

error: integer out of range for 'L' format code

could you please let me know if it is the right version to be used? I
couldn't find RipL and RipLPOX at POX git repository. Or could you please
suggest me a fix for this problem? Thanks a lot for your help/suggestions.
Regards,
David
