[dpdk-dev] L2/L3 FWD App

Hi,

I am a newbie at DPDK, just trying to get some basic applications to run to
understand it. One of the apps that I have been trying to run is provided
with the source code i.e. L3 FWD App. Are there any changes which I should
be hard coding in the file for it to work?

>From what I understand, I have to hard code a rule for LPM (<dst_ip>,
depth/subnet, output interface) in "ipv4_l3fwd_route_array". The
destination IP is matched with the destination IP field of the incoming
packet and the output port refers to the NIC port itself. I have tried
running this application this way, but I do not see any packets being
forwarded to my receiver.

Are there any other changes I need to make?
I am using Ostinato as the traffic generator. I am generating ICMP packets
with dst_MAC=MAC address of the NIC port.

Any help or heads up would be appreciated, thanks.
Best regards

Hi,

The problem was that VT was enabled in the BIOS. I went through FAQs and
saw the solution there. Just replying back on my thread in case someone
runs into this problem. This resolved my issue, the application is working
fine.

Thanks and best regards.
