It's based on a great deal of real-world experience; I'm sorry you consider that to be 'ignorant'.

Anti-spoofing, iACLs, CoPP (or its equivalent on non-Cisco platforms), et. al. aren't 'misinformation'.  They're 
useful, proven techniques/features which any operator ought to implement.

Then your experience of Cisco routers (and/or those from other vendors) must be limited to the lower-end platforms; I 
can assure you that faster Cisco boxes such as ASRs, GSRs, CRSes, and so forth are in another league entirely, and can 
handle mpps of to-us traffic, when properly configured.  Software-based routers simply can't do that; it's not an 
indictment of them, it's just that they aren't suited to purpose, just as station wagons generally aren't to be found 
in the Indy 500.
