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",
"mode": "hot-standby",
"heartbeat-delay": 10000,
"max-response-delay": 10000,
"max-ack-delay": 5000,
"max-unacked-clients": 5,
"peers": [
{
"name": "our_name01",
"url":
"http://our_address:8080/<http://100.64.47.244:8080/>",
"role": "primary",
"auto-failover": true
},
{
"name": "our_name02",
"url":
"http://out_address:8080/<http://100.64.47.245:8080/>",
"role": "standby",
"auto-failover": true
}
]
} ]
}
}
],
}
}
Let me know if you need any more info
