ia-pd and ia-na T1 and T2 values #9

Closed djzort closed 1 year ago

djzort commented 5 years ago

Is there any way to set the T1 and T2 values for ia-pd and ia-na options?

The doco doesnt seem to have a way, im about to dive in to the code...

djzort commented 5 years ago

As far as i can tell theyre hard coded to 0

I looked at this a while ago with @marjohn56.

Its a significant effort to add this to dhcp6c and as its ignored by most ISP's anyway it was assumed to not be worth the effort right now. Are you seeing issues ?

djzort commented 5 years ago

I believed this to be the cause of problems, but it turned out to be unrelated. If there is no way currently, then you have answered my question :)

It does look like opnsense is the only people giving wide-dhcp6 any love (and only a little bit) - perhaps the isc client via the dual-dhclient port would be better?

nivek1612 commented 5 years ago

there has been a huge amount of work from the team on it. :-)

Before they did this work many of the dhcp6c options where not passed but now Raw-options are supported fully.

so whilst you can't send T1 & T2 as options you can build a raw-option 25 which is made up of IAID, T1 & T2

Timeout.

Hi! I think this is causing my ISP to ignore the message too. Maybe @djzort what was the reason of your problem?

Basically I'm looking in wireshark dhclient -6 -P is working: Capture d’écran 2024-01-18 à 12 30 26

And with dhcp6c: Capture d’écran 2024-01-18 à 12 34 02

I don't see anything else different, except maybe the FQDN request missing. My ISP is Proximus (Belgium).

It also seems the link layer address being advertised is wrong. I'll open a dedicated issue.
