I think Eder has it all right. The message in question is nx_role_request, and it is available in the POX carp branch.
Using Nicira / OVS extensions in POX is currently not documented very well, but there is an entry for it in the manual and a component or two which use them (e.g., forwarding.l2_nx). Best bet at the moment is reading OVS documentation, the OVS source files (especially nicira-ext.h, which you can find on Google easily), and pox.openflow.nicira (where all the POX code for it lives). Luckily, nx_role_request should be pretty easy to use. -- Murphy On Sep 19, 2013, at 1:13 PM, Windhya Rankothge <[email protected]> wrote: > Thanks alot for the information..
