[Olsr-users] Missing mandatory TLV 25 in extension 256

[Mika Rajala]

Well, I don’t know how much better I can try to describe the issue than this message I already sent, did you read this one?

That is one message, I just broke it into lines to make it easy to read.

I suppose that dlep_radio should read the extensions I support from my Session Init Response Message, but I can't find that.

Maybe it's because mine doesn't have the "Supported Extensions" tlv with an empty list?

I'm using 0.10 or something, maybe this has already been fixed?

By barebones, I mean a one that implements only the mandatory fields and nothing more. I do think that It's likely that my implementation does it wrong.

I have a little bit trouble reproducing the problem with my own DLEP radio code.

I disabled the two extension in the DLEP radio (and on a second test in the DLEP router) and in both cases I just got a normal handshake

(without the additional metrics of course)

What do you mean with "barebone" ?
