1. Ubuntu 16.04
2. apt-get install  kea-dhcp4-server
3. install library  : kea-sdnc-notify.so  (/usr/local/lib)
1. this library is built from source (hacked up copy of kea-pxe-replace4-mod)
2. creates the hook which listens on pkt4_send
3. sends an HTTP POST via libcurl if message is DHCPACK (that is response to client after Discover/Offer/Request)
4. POST has macaddr, msg_name,  yiaddr (yiaddr is the one we want in SDNC)
5. No response required since we are not re-writing the packet

1. install conf files:
1. /etc/kea/kea-dhcp4.conf

                                                    i.     This file sets ups the giaddr and ip blocks to be served

                                                   ii.     In the demo its 192.0.2.0/24

1. /etc/kea/kea-sdnc-notify.conf

                                                    i.     This file sets the desintation url

                                                   ii.     For testing “http://localhost/sdnc.php?macaddr=”

                                                  iii.     For ONAP it would be a DMaaP TOPIC

1. Start kea-dhcp4-server
2. Logs in /var/log/kea-dhcp4.log

Yes. I’ve kept SNIRO Functionality, all that is needed is to add a user param of Name:”Homing_Solution” Value:“sniro” when instantiating the vCPE service. If ”Homing_Solution” user param is omitted, or has value:”oof” it will use new homing/OOF flow. To use OOF the userParam “Customer_Location” is also needed.

Here is an example rest request, with user param highlighted:
