I had trouble parsing "output it to or queue it for" (this occurs twice
in the sentence).

   However, it does not output it to or queue it for that link,
   although, if appropriate (for example, the frame is multi-

   3.2.1 Change Optimization One

   3.2.2 Change Optimization Two

   3.2.3 Settling Detection Optimization

   For robustness, a TRILL switch sends a number of copies of a Port-
   Shutdown messages configurable from one to three, which defaults to
   two copies, at a configurable interval, which defaults to 20
   milliseconds (see Section 6.6).

difficult to parse. Perhaps

   For robustness, a TRILL switch sends a configurable number of copies
   of Port-Shutdown messages separated by a configurable interval. The
default
   number of copies is two, although this can be configured as one copy
   or as three copies, and the default interval is 20 milliseconds 
   (see Section 6.6).
