Hi:
These values can be used to set limits on lifetimes requested by
clients. This allows you to make sure client's do no request values
that are too small or too large for your requirements. If you do not
set them, they default to valid-lifetime which effectively ignores
requested client lifetimes.

Thanks Thomas,
But I still a bit confused about default to min-valid-lifetime and
max-valid-lifetime.

Hello:
You need only set calculate-tee-times to true. The percentage values,
t1-percent and t2-percent, default to .5 and .875 respectively.

Hi,
1 - "Beginning with Kea 1.6.0 the lease valid lifetime is extended
from a single value to a triplet with minimum, default and maximum
values using |min-valid-lifetime|, |valid-lifetime| and
|max-valid-lifetime|. When the client does not specify a lifetime
the default value is used, when it specifies using a DHCP option
code 51 this value is used if it is not less than the minimum (in
this case the minimum is returned) or greater than the maximum (in
this case the maximum is used)."
What is the default value for |min-valid-lifetime| and
|max-valid-lifetime| ?
I presume |valid-lifetime| right ?
2 - "According to RFC 2131 <https://tools.ietf.org/html/rfc2131>,
servers should send values for T1 and T2 that are 50% and 87.5% of
the lease lifetime, respectively. By default, kea-dhcp4 does not
send either value. It can be configured to send values that are
specified explicitly or that are calculated as percentages of the
lease time."
So explicitly :
# DHCPv4 configuration starts on the next line
"Dhcp4": {
# First we set up global values
"valid-lifetime": 4000,
"renew-timer": 1000,
"rebind-timer": 2000,
And calculated as percentages :
# DHCPv4 configuration starts on the next line
"Dhcp4": {
# First we set up global values
"valid-lifetime": 4000,
|"calculate-tee-times": true, |
Or :
||
# DHCPv4 configuration starts on the next line
"Dhcp4": {
# First we set up global values
"valid-lifetime": 4000,
|"calculate-tee-times": true, | ||"t1-percent": 0.5, "t2-percent": 0.875,||
It's the right way?
Best,
