Hi Folks - Due to the feedback we've received on the Autosecure bogon list issue, we've decided to do the following: 1) Provide a fix that removes bogon ACL creation and deployment from the Autosecure feature. This change will be available in mainline and maintenance software releases. For the software release details, please refer to 2. 2) A Cisco Field Notice will be published to inform customers of the change and will contain instructions on how to remove the bogon ACLs created by executing the autosecure command. We'll update the list with the Field Notice URL as soon as it's available. Tentative date for FN posting is 18th February 2005. Regards. /kunjal

I think that Cisco's Autosecure feature is part of the problem here:

While it says that bogon filters change, and provides a URL to check it, what percentage of folks who would use a feature like "autosecure" would ever update their filters?
sigh.
