Patching for Cisco vulnerability

Fri Jul 18 21:20:22 UTC 2003

What kind of testing protocol do providers have in place to test IOS
images prior to deployment.  I have never been exposed to those
processes and am curious to understand what takes place as a BCP.

	most providers can easily go from (for example)
12.0(21)S3 to 12.0(21)S7 with less testing than from 12.0(21)S to
12.0(25)S

	The hurdles are still there to maintain the necessary
customer notifications, etc.. but aside from that, I think the press is
doing their job (good or bad) in that most customers are aware that
there's something bad going on and people are moving to protect the
internet infrastructure.
