Re: Bogon filtering (don't ban me)

In Ciscoland its called Autosecure (IOS 12.3):
http://www.cisco.com/warp/public/cc/pd/iosw/prodlit/cas11_ds.htm

"Blocks all IANA reserved IP address blocks"

The actual doc:
<http://niatec.info/mediacontent/cisco/media/targets/resources_mod07/7_1_2_AutoSecure.pdf>

Problem is, I still do not see that Cisco has a way of auto-updating a
router that has used autosec_complete_bogon or
autosec_iana_reserved_block.

We've proposed what vendors need to better support bogon filtering, even
wrote a draft:
  http://arneill-py.sacramento.ca.us/draft-py-idr-redisfilter-01.txt
but last time I talked to cisco ios person (which was just two weeks ago
at IPv6 Summit), it still has not been done. Perhaps couple more people
who buy their hardware asking them about it will make a difference ...
