[Kea-users] Configuring HA with multiple interfaces on both the appliances

[Kraishak Mahtha]

 Hi all,
 I have a few doubts in a case where we have multiple interfaces listening
in the kea dhcp and configured in HA/Failover mode.
For instance: I have server A with four interfaces
 eth0 (192.168.0.51), eth1 (192.168.0.52), eth2 (192.168.0.53), eth3
(192.168.0.54) and server B I have three interfaces
eth1(192.168.0.61), eth2(192.168.0.62), eth2(192.168.0.63).

Case 1) Can we define failover configuration with servers A and B
specifying server A listening on three interfaces and server B listening on
two interfaces? (no same number of interfaces on both appliances).

Case 2) When we have such a configuration how do we deal with the failover
configuration where we specify only one IP?
"peers": [
            {
                "role": "primary",
                "name": "dhcp1",
                "auto-failover": true,
                "url": "http://192.168.0.51:8001"
            },
            {
                "role": "secondary",
                "name": "dhcp2",
                "auto-failover": true,
                "url": "http://192.168.0.61:8001"
            }
       ],
Should we specify all the listening interface IP's in the failover section?

Can someone who is familiar with such setups and has faced similar issues
guide me?

Thanks in Advance
Kraishak
