+vpp# hicn ?
+```
+
+`hicn control param`: configures the internal parameter of the hICN plugin. This command must be run before hicn control start.

+ <strategy_id> :set a strategy for the corresponding prefix
+```
+
+`hicn mapme`: enable and disable mapme.
+
+```
+hicn mapme {enable|disable|set <param> <value>}
+```
+
+
+`hicn pgen client`: set an vpp forwarder as an hicn packet generator client

+ <face_id> :id of the face to set the weight
+ <weight> :weight
+```
+
+#### hICN plugin configuration file ####
+
+A configuration can be use to setup the hicn plugin when vpp starts. The configuration file is made of a list of CLI commands. In order to set vpp to read the configuration file, the file /etc/vpp/startup.conf needs to be modified as follows:
+
+```
+unix {
+ nodaemon
+ log /tmp/vpp.log
+ full-coredump
+ startup-config <path to configuration file>
+}
+```
+#### hICN plugin binary api ####
+
+The binary api, or the vapi, can be used as well to configure the hicn plugin. For each cli command there is a corresponding message in the binary api. The list of messages is available in the file hicn.api (located in hicn/hicn-plugin/src/)
+
+### Example: consumer and producer Ping ###
+
+In this example, we connect two vpp forwarders, A and B, each of them running the hicn plugin. On top of forwarder A we run the ping_client application, on top of forwarder B we run the ping_server application. Each application connects to the underlying forwarder through a memif-interface. The two forwarders are connected through a dpdk link.
+
+#### Forwarder A ####
+
+```shell
+$ sudo vppctl
+vpp# set interface ip address TenGigabitEtherneta/0/0 2001::2/64
+vpp# set interface state TenGigabitEtherneta/0/0 up
+vpp# hicn control start
+vpp# hicn face ip add local 2001::2 remote 2001::3 intfc TenGigabitEtherneta/0/0
+vpp# hicn fib add prefix b002::1/64 face 0
+vpp# hicn punting add prefix b002::1/64 intfc TenGigabitEtherneta/0/0 type ip
+```
+
+#### Forwarder B ####
+
+```shell
+$ sudo vppctl
+vpp# set interface ip address TenGigabitEtherneta/0/1 2001::3/64
+vpp# set interface state TenGigabitEtherneta/0/1 up
+vpp# hicn control start
+vpp# hicn punting add prefix b002::1/64 intfc TenGigabitEtherneta/0/1 type ip
+```
+
+Once the two forwarder are started, run the ping_server application on the host where the forwarder B is running
+
+```shell
+$ sudo ping_server -n b002::1
+```
+
+and the client on the host where forwarder B is running
+
+```shell
+$ sudo ping_client -n b002::1
+```
+
