[BB] Thank you. It sounds like you have some reason for your certainty here. Can you elaborate on what makes you so certain sequencing isn't used? <tp> Perhaps a coincidence or perhaps not, but an I-D has just been posted Author : Yogesh Nautiyal Filename : draft-nautiyal-l2tpext-tunnel-ka-control-channel-00.txt which uses L2TP sequencing, I note the author has an affiliation of Juniper. The draft would need a fair bit of work.
