COMMENT:
----------------------------------------------------------------------

Thank you to Joseph Salowey for the SECDIR review.

Thank you to the authors for the implementation report pointer
(draft-matsushima-spring-srv6-deployment-status)

I support Alvaro Retana’s DISCUSS position.

I also support Warren Kumari’s DISCUSS position.  In particular, discussing the
magnitude of the exposure of an internal topology due to a BGP leak would be
helpful to document.

** Section 8.  It would be worth repeating the two key security assumptions
from RFC8402:

OLD
SRv6 operates within a trusted SR domain with filtering of traffic at
   the domain boundaries.

NEW
SRv6 operates within a trusted SR domain with filtering of traffic at the
domain boundaries. Likewise, there is an assumed trust model such that any node
adding an SRH to the packet is assumed to be allowed to do so.
