Summary: Ready with issues
--------

Comments: 
---------

I agree with the point raised in the Routing Area review
(be explicit about the updated sections of RFC 6514, 6625,
and 7524).

Minor issues:
-------------

As I understand it, if a network only partially supports the new
(LIR-pF) flag, it doesn't work properly. So we find at the end of
section 2:

...the ingress node can conclude
   that the egress node originating that Leaf A-D route does not support
   the LIR-pF flag.

   The software at the ingress node SHOULD detect this, and should have
   a way of alerting the operator that the deployment is not properly
   configured.

I don't see why this is only a SHOULD, and I don't see why the operator
alert is not a MUST too. Surely the operator always needs to be alerted?
