===================================
The IPv4 Fragmentation application is a simple example of packet processing
-using the Intel® Data Plane Development Kit (Intel® DPDK).
+using the Data Plane Development Kit (DPDK).
The application does L3 forwarding with IPv4 and IPv6 packet fragmentation.
Overview
--------
The application demonstrates the use of zero-copy buffers for packet fragmentation.
-The initialization and run-time paths are very similar to those of the L2 forwarding application
-(see Chapter 9 "L2 Forwarding Simple Application (in Real and Virtualised Environments)" for more information).
+The initialization and run-time paths are very similar to those of the :doc:`l2_forward_real_virtual`.
This guide highlights the differences between the two applications.
There are three key differences from the L2 Forwarding sample application:
export RTE_TARGET=x86_64-native-linuxapp-gcc

#. Build the application:
.. code-block:: console
- ./build/ip_fragmentation -c 0x14 -n 3 -- -p 5
+ ./build/ip_fragmentation -l 2,4 -n 3 -- -p 5
EAL: coremask set to 14
EAL: Detected lcore 0 on socket 0
EAL: Detected lcore 1 on socket 1
.. code-block:: console
- ./build/ip_fragmentation -c 0x10 -n 3 -- -p 5 -q 2
+ ./build/ip_fragmentation -l 4 -n 3 -- -p 5 -q 2
To test the application, flows should be set up in the flow generator that match the values in the
l3fwd_ipv4_route_array and/or l3fwd_ipv6_route_array table.
in that all the memory structures are allocated on all sockets that have active lcores on them.
