Hi, all. I'm trying to show how to forwarding table is installed.
I'm using 3 Lithium controllers and each controller(c1, c2, c3) have 1 switch(s1, s2, s3) c1 c2 c3 l l l s1-s2-s3 and ping s1 to s3 I have two questions about above test. 1) As I know, only when the new packet came in to switch, switch send Packet_in message to controllers. and then controller send Flow_mod message to switch to forwarding new packet. but when I command s1 ping s3, Packet_in message is occurred periodically (5 seconds), and there is no Flow_mod message, Is this right operation? 2) In clustering environment, Do all switches between the source and destination are sending packet_in message to the controller ? thanks.
