It gets even worse. Cisco has hard-coded the list of Bogons into some of

Yes, Cisco includes warnings in the manual the user should check the
official list at IANA; but I also know the power of defaults. People
upgrade their IOS versions even less often then they update their
Windows boxes. So we're going to see chunks of the net blocked depending
on the release date of versions of IOS.
There is an old saying which seems to fit here;
