RE: Eric Rescorla's No Objection on draft-ietf-rtgwg-uloop-delay-07: (with COMMENT)

[<[e-mail]>]

Hi Eric,

Thanks for your review, I will take care of your comments.

" Line 136
   When S-D fails, a transient forwarding loop may appear between S and
   B if S updates its forwarding entry to D before B.
Something seems to have gone badly wrong with this paragraph. Are these lines supposed to be in the previous paragraph."

[SLI] This is the postamble of the figure and not really a paragraph.


"             Figure 7
Is this the same as the previous figure with T running CEAB?
"

[SLI] What figure are you talking about when saying "the previous" ?
I think there is a copy/paste issue. The tunnel T is not used here.


Brgds,

Line 115
   Consider the case in Figure 1 where S does not have an LFA to protect
   its traffic to D.  That means that all non-D neighbors of S on the You need to define LFA.
