i understand bogon filters and reasoning behind it and i'm all for it.
but why does one think (maybe i missing something) this approach
(autosecure) is scalable and acceptable to update your ios or even
constantly updating your acls every time one has to update their bogon
filters? yet another think to look out for? i like to see the network
availability for aol, google, nasdaq, every time they update their bogons.

why can't this somehow be dynamically updated and /or linked to a
master file as opposed to upgrading the ios?

like to hear more thoughts on it.
