Hi Xiaohu- This is a very interesting draft. I haven't seeing a lot of comments on this, do you have any update how it is progressing? I have a question about VRF, if the tunnel termination would be bound to a VRF, is there any mechanism to signal what routing table does the lookup needs to happen? Do we need a set of source/dest pairs per VRF?
