Yeah. A DOTS gateway may be embedded in the access router. That’s said, we need to distinguish between the @es to reach the DOTS agents vs. the ones signaled in the DOTS messages (which belong to the attack sources).

An example of the use of link-local @ses is what is hinted in Éric's review: "if the CPE is a layer-2 node".

Cheers,
