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): File "/root/pox/pox/lib/revent/revent.py", line 231, in raiseEventNoErrors return self.raiseEvent(event, *args, **kw) File "/root/pox/pox/lib/revent/revent.py", line 278, in raiseEvent rv = event._invoke(handler, *args, **kw) File "/root/pox/pox/lib/revent/revent.py", line 156, in _invoke return handler(self, *args, **kw) File "/root/riplpox/riplpox/riplpox.py", line 344, in _handle_PacketIn self._handle_packet_reactive(event) File "/root/riplpox/riplpox/riplpox.py", line 240, in _handle_packet_reactive self._install_reactive_path(event, out_dpid, out_port, packet) File "/root/riplpox/riplpox/riplpox.py", line 160, in _install_reactive_path IDLE_TIMEOUT) File "/root/riplpox/riplpox/riplpox.py", line 90, in install self.connection.send(msg) File "/root/pox/pox/openflow/of_01.py", line 692, in send data = data.pack() File "/root/pox/pox/openflow/libopenflow_01.py", line 2320, in pack self.flags) error: integer out of range for 'L' format code INFO:.root.riplpox.riplpox:route: ['0_1_1', '0_2_1', '0_0_1'] 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.
