I wonder if a device, after a reboot having a previous known configuration, uses it from the start even tho it's still asking to check if it can continue using that configuration...or not.
I mean, at the very start after a reboot, will the device maintain the configuration or not? The device needs to ask the DHCP server if it can maintain that configuration or not, but in that process, it needs to have a configuration right?
Also, in the rebooting process, the different Times are also taken into account? (T1, T2, T3). I'm guessiing that after a reboot the device enters automatically into T1, because it's asking, but if that specific DHCP server won't ask...will it enter T2 and make a broadcast request to any DHCP server in that network? And if nobody answers will it reach T3 and become unconfigured?
Basically, what I'm trying to understand is that if during the rebooting process, the above process it's still being done (requesting, renewing, rebinding...etc etc). Also, if after a reboot you maintain the configuration or not (despite the fact that you need to ask the DHCP if you can keep it or not).
