Openflow Controller Arp Packet Flooding forever (Even after correct resolution).

[Vikash B]

Hi All,

I am Using Latest ns3 release ns-3.26.

I am just testing how openflow works: The existing openflow example uses a single switch, so i created an example with two switches.

Here is my topology:

                         Controller (Learning Controller)

                              /  \

               n1 -- ------    ------- ----n3

                        | S1 |--| S2 |                               ONOFF application source n1, destination = n2

               n2 --  ------   -------  ---n4

The example with single switch works fine, but the example with two switches floods ARP packet for infinite time, long after the application has stopped.

From the logs i can see that the ARP requests are being resolved and the correct IP is matched to the correct MAC address.

I don't understand what i am doing wrong, Do i have to modify the Learning Controller to Drop ARP packets or something?

Any help would be really appreciated.

Thanks.
