Hi Matthew,
Per Perlman "Interconnections, 2nd Ed." p 306 - "Poison reverse means
reporting a value of infinity to explicitly report that you can't reach D
rather than simply not mentioning D." So, instead of not acknowledging
something, the issue in question is acknowledged, but with an answer that is
not valid, thus 'spoiling' the output.
Is this what you are asking or are you asking why was 'poison' chosen
instead of words such as 'corrupt' or 'defile'?

Subject: Off topic, What does "Poison" mean here?
Dear All,
We may be familiar with "Route Poisoning" or "Poison Reverse". But what does
"poison" mean here? As I imagine, there may be 2 answers
1. The name of a French mathematician. He invented the algorithm, which is
used in Distance Vector routing protocol now.
2. Another expression way of "block".
Which one is correct? Or maybe some other answers?
Matthew Ma
