Hi,
I'm using Kea 1.6.3 to assign IPv6 addresses to endpoints which support rapid-commit only. The addresses are assigned but I do see the following warning messages in the logs:
2020-11-24 21:26:58.831 INFO [kea-dhcp6.leases/1] DHCP6_LEASE_ALLOC duid=[00:03:00:06:00:17:3b:10:00:44:00:21], tid=0xa852e0: lease for address fd10:5::1 and iaid=0 has been allocated for 2592000 seconds

We can see the assigned addresses being added to the leases file:

My subnet6 config is the following:
{
"calculate-tee-times": true,
"id": 201,
"option-data": [ ],
"pd-pools": [ ],
"pools": [
{
"option-data": [ ],
"pool": "fd10:5::1-fd10:5::ffff:ffff:ffff:fffe"
}
],
"preferred-lifetime": 2592000,
"rapid-commit": true,
"relay": {
"ip-addresses": [ ]
},
"reservation-mode": "all",
"reservations": [ ],
"subnet": "fd10:5::/64",
"t1-percent": 0.5,
"t2-percent": 0.8,
"valid-lifetime": 2592000
},
Should I be worried about those warnings or I can safely ignored them ?
Thanks for your support
