Hi all,
Was it you that gave that talk? The DEI bug was fascinating! (and my fingers keep wanting to type that as DIE bug)
I did glaze over at which points in the fiber network it was occurring in and on what technologies... is there a pdf of your talk available?
And a question that I didnt get a chance to ask was why/when/how does the end user device assert this bit at all?
That was me. In all honesty it probably should have been a real talk rather than a lightning talk in the end. Was a lot of information to convey. The DEI bit was generated by Chorus (our main fibre operator here) for traffic outside of the CIR (2.5mbit L2). We then believed at some stage in our network we were dropping it. It ended up being an MPLS backbone of another operator that we used that was dropping the DEI marked packets but only because we were re-writing from the inner L2 to the outer L2. Happy to talk on or off list if you want more details. There's also a very long NZNOG thread about it back in July last year where I state some facts and make up some as well :) I am about to disappear for a couple of days though so replies might be delayed. Go the Black Caps! Cheers Dave
