Operatin System: 14.04.5LTS Ubuntu. You can get from http://releases.ubuntu.com/14.04/
VPP:vpp17.07 rc0 use git clone https://gerrit.fd.io/r/vpp -b v17.07-rc0
Cuckoo files: cuckoo.c and cuckoo.h

1) Run the command pstree –p to check if init is ps 1.
If not you are probably using systemd. Install upstart instead
2) Go to your install directory for vpp. Run the following command:
git clone https://gerrit.fd.io/r/vpp
3) Enter directory vpp. Run command “git describe” to check the version of vpp.
4) Navigate to vpp/build-root/vagrant
5) Run the command ./build.sh. Wait for the build process. Look out for errors. Vpp-api-python error can be ignored. Though if its required install python dev package.
6) Execute sudo dpkg –i /vpp/build-root/*.deb 
6) Read startup.conf file. Run the command: more /etc/vpp/startup.conf. Read the comments and understand the sections of the file, especially NIC whitelists

Putting​ ​ the​ ​ cuckoo​ ​ files​ ​ into​ ​ vpp.
The​ ​ /vpp/src/vnet/util​​ ​ folder​ ​ contains​ ​ the​ ​ cuckoo​ ​ files
Also​ ​ it​ ​ is​ ​ not​ ​ enough​ ​ to​ ​ simply​ ​ copy​ ​ the​ ​ files​ ​ into​ ​ the​ ​ above​ ​ location.
We​ ​ need​ ​ to​ ​ modify​ ​ the​ ​ “ ​ vnet.am​ ” ​ ​ file​ ​ in​ ​ /vpp/src/​ ​ ​ as​ ​ below
nobase_include_HEADERS​ ​ +=​ ​ cuckoo.h
libvnet_la_SOURCES​ ​ +=​ ​ cuckoo.c

Now​ ​ we​ ​ have​ ​ call​ ​ our​ ​ cuckoo​ ​ filter​ ​ functions​ ​ to​ ​ create​ ​ the​ ​ filter​ ​ and​ ​ insert​ ​ routes​ ​ into​ ​ the
filter​ ​ and​ ​ do​ ​ lookups​ ​ in​ ​ the​ ​ filter​ ​ etc.
To​ ​ do​ ​ these ​ we​ ​ need​ ​ to​ ​ modify​ ​ the​ ​ ip6_forward.c​​ ​ file​ ​ in​​ ​ /src/vnet/ip​​ ​ folder
Also​ ​ you​ ​ will​ ​ need​ ​ to​ ​ modify​ ​ the​ ​ ip.h,​ ​ ip6.h​ ​ , ​ ​ ip6_fib.c​ ​ , ​ ​ ip6_fib.h​ ​ , ​ ​ fib_table.h​ ​ files​ ​ under
the​ ​ /src/vnet/ip​​ ​ or​ ​ /src/vnet/fib​​ ​ folders.

sudo start vpp
sudo vppctl exec "file name to add routes in filter and routing table"
sudo vppctl clear lookup
sudo vppctl set cuckoo
sudo vppctl exec "lookup file"
sudo vppctl show ip6 lookup
