[Int-area] Intarea review needed: short draft on ECN propagation IP-shim(s)-IP

[Bob Briscoe <[e-mail]>]

Intarea list,

I presented this short draft just under a year ago in intarea. Since 
then it has been adopted as a tsvwg work item.

I have just added specific text to update those tunnel specs that are 
under IETF change control (L2TP and GRE), as well as addressing non-IETF 
specs too (VXLAN, GTP, NVGRE etc).

I would appreciate review from someone in intarea who knows these specs 
better than I do.

If you know L2TP well, pls check the l2tpext list, where I have just 
posted three L2TP-specific question.


Cheers


Bob
