Introduction  

Dhcp Manager Support has been brought in completely for both ipv4 and ipv6 in Bannapi R4.This page shares information about code changes and test results done for the integration of dhcp manager in BPI R4.

RdkDHCPManager is a component in RDK-B OS responsible for configuration and command control of DHCP client and server for both IPv4 and IPv6.



Code Changes : 

We need to do the following code changes to integrate Dhcp Manager in the Bananapi R4 platform


 2.1.Enable both the dhcp manager and configurable wan interface distro features in our configuration file for this feature to work seamlessly,


DISTRO_FEATURES_append = " dhcp_manager "
DISTRO_FEATURES_append = " rdkb_configurable_wan_interface"


   

2.2.Register dhcp manager in CR 

     <component>
      <name>eRT.com.cisco.spvtg.ccsp.dhcpmgr</name> <version>1</version>
    </component>    
    </components>


     2.3 Enable the Cflags for both the distros in the ccsp_common.inc file


  CFLAGS_append  += " ${@bb.utils.contains('DISTRO_FEATURES', 'dhcp_manager', '-DFEATURE_RDKB_DHCP_MANAGER', '', d)}"
  CFLAGS_append  += " ${@bb.utils.contains('DISTRO_FEATURES', 'rdkb_configurable_wan_interface', '-DFEATURE_RDKB_CONFIGURABLE_WAN_INTERFACE', '', d)}"


      2.4 Updating the psm data base
