Thanks Marcin.
So I guess a hook would be the next best way to do that.
Something configured like:
"Dhcp4": {
:
"hooks-libraries": [
{
"library": "/opt/local/multi-relay-subnets.so",
"parameters": {
"relay-subnets": [
{
"subnet": "192.0.2.0/26",
"relays": [ "192.1.1.1", "192.2.2.2" ]
},
{
"subnet": "...",
"relays": [ ... ]
}
]
}
}
]
}
A hook "subnet4_select" which would:
- loop over the hook parameter "relay-subnets" to find a suitable entry for the
received giaddr,
- and then loop over Kea "subnet4collection" to retrieve the subnet we want,
- and set that in the callout argument "subnet4".
I've seen something similar discussed on the mailing list:
