I have to congratulate you on finding this documented somewhere. When
I first ran across it, I happened to be at the IETF meeting, so,
after a quick CCO look didn't come up with it, I asked the IOS
developers with whom I was having dinner if they knew what did it.
The first said he had seen it but wasn't quite sure what caused it.
He turned to a colleague (in fairness, both of these were routing
protocol specialists), who said he thought it had to do with PPP, and
there was a command with peer in it. We were able to snag a PPP
developer the next day and get the answer.
Definitely an obscure question, but one of those things that could zap you.
