[straw] AD review of draft-ietf-straw-b2bua-loop-detection-04

[Richard Barnes <[e-mail]>]

I have reviewed this document in preparation for IETF LC.  Overall, it
looks good to me; I have requested LC.  One editorial nit and one comment
below.

Thanks,

In Section 5, the antecedent of "which SHOULD be 70" appears to be the
generated Max-Forwards header, so this doesn't really parse.  "The value
for this header field SHOULD be 70..."

In the security considerations, you mention resetting the Max-* headers. Is
there a way this could be done that is compatible with the goals of this
doc?  E.g., setting any random value for Max-Forwards, as long as it's
lower than what came in?  Allowing something like this could bring more
proxies into conformance with the overall objective of this document.
