Kea has about the best High Availability functionality I've used!

 

Our setup is 2 kea servers each with it's own PSQL server.

 

It looks like this, only difference between the two being the name.

    "Dhcp4": {

"control-socket": {

         "socket-type": "unix",

         "socket-name": "/tmp/kea-dhcp4-ctrl.sock"

     },

"hooks-libraries": [

            {

                "library": "/usr/lib64/kea/hooks/libdhcp_lease_cmds.so",

                "parameters": { }

            },

            {

                "library": "/usr/lib64/kea/hooks/libdhcp_ha.so",

                "parameters": {

                    "high-availability": [ {

                        "this-server-name": "our_name01",

                                "role": "primary",

                                "auto-failover": true

                            },

                            {

                                "name": "our_name02",

                                "url": "http://out_address:8080/ <http://100.64.47.245:8080/> ",

                                "role": "standby",

                                "auto-failover": true

                            }

                        ]

                    } ]

                }

            }

        ],

}

}
