Thanks Martin, So it just to do this work ? and other question, (Q1) What information will be get? Such as, this switch IP, the neighbor node IP, or something. (Q2) This LLDP packet sends by who? Is controller or switch. (Q3) If it is switch to do this work, then it is every switch to do it? or just one ...
Because I have ever see this in the openflow switch website. http://www.openflowswitch.org/wk/index.php/OpenFlow_v1.0#Neighbor_Discovery Sorry, I really want to know. Thank you so much.
