[dpdk-dev] test setup for l3fwd application running on VM

[B Gopikrishna]

Update on the below query :
When DPDK is not running,we have the setup working i.e. the TCP client and server as per the below setup are communicating properly.

So now we started DPDK and ran the L3fwd application in VM2, added an arp entry on VM1. Modified the lookup table in l3fwd code as per our setup. Not sure whether the 0  (the if_out) at the end of this entry represents vnic1 or vnic2. Though we tested with both 0 and 1 entries.

{{IPv4(101,0,0,2), IPv4(100,10,0,1),  5000, 6000, IPPROTO_TCP}, 0},

The tcp client is binded to 6000 port and server is binded to 5000. These values are also modified in l3fwd app.

Are we missing something else. Please let us know. Thanks in advance for the help.


VM1                                 VM2(DPDK-L3fwd)                                VM3
vnic1 ------bridge1 --------vnic1             vnic2------bridge2--------vnic1
100.10.0.1                  100.10.0.2        101.0.0.1                        101.0.0.2
(port: 6000)                                                                              (port: 5000)

Subject: test setup for l3fwd application running on VM



Hi
I have the below setup and would like to check the l3fwd application running on VM 
 
VM1                                 VM2(DPDK-L3fwd)                                VM3
vnic1 ------bridge1 --------vnic1             vnic2------bridge2--------vnic1

 
On VM1 -TCP client and, on VM3 -TCP server applications are running
The TCP client and server should communicate via the DPDK L3fwd application running on VM2.
 
I created a static arp entry on VM1 in order that the packets reach VM2 vnic1, and then the DPDK-L3fwd app would take care of forwarding the packets to VM2 vnic2, and further the packets reach VM3 vnic1
 
This is not working for me, please let me know if I need to do some additional steps in order to complete the flow.
 
All the vnic's are configured as e1000 drivers.
