Perhaps it will be better to specify the "relay" parameter on the subnet
level:

"relay": {
    "ip-address": "100.101.101.0"
}

See: http://kea.isc.org/docs/kea-guide.html#dhcp6-relay-override

The classification will be needed for filtering the RAI option values to
more specifically select the subnet but relay parameter should narrow
down the selection for the relay address.
