Anantha also posted this question in the LAN Switching and Routing forum where there was an interesting discussion and a demonstration that this is an absolutely valid extended access list when used in a distribute list in BGP.

Hi, there is a very strong possibility that the person that entered this command didn't had a clue about what he/she was doing, as it doesn't seems to have any practical applications.
Sometime people with a territorial attitude intentionally enter obscure and unnecessary commands, in order to retain authority in the workplace. This may or may not be the case here.

Rick, of course you are correct.
I had forgot about the old technique where source matches prefix and destination matches prefix-length, that predates the current prefix-list.
A more complete config snippet would have prevented the confusion for which I apologize.

Absolutely right !
The first thing that I said in my response in the other forum was to ask about the context of using the access list. If it had been mentioned that it was a BGP distribute list then there would have been no confusion.
