Thanks. Are you sure FPM is supported on IOS-XR? I'm not finding any
evidence of that. I'm not finding any evidence that it is supported on
Juniper PTX boxes, either, and the story for MX boxes seems confusing.

Since this is critical to enabling operators (not participating in an
experiment) to protect themselves from L4S traffic, it would be
worthwhile to confirm this capability is widely available on deployed
gear. Perhaps the draft could include some configuration information in
an appendix?
