Hi Daniel,
CEF shouldn't break anything, apart from a few (very rare) bugs that can
sometimes cause problems.
At the place where I work we have turned on CEF on all backbone routers
since the "Code Red invasion". Standard IP route caching can have serious
memory impacts (free memory and fragmented memory) during a worm breakout.
IMO there is nothing wrong with enabling CEF by default (apart from somebody
that told me that a 2500 routers CPU is not fast enough to always support
it, but I haven't verified this myself).
Kind regards,
Koen.

Subject: cef musings...
My question is, for the lab, is there something I am missing that would
'break' if ip cef was turned on regardless?
And, more importantly, since this is my job as well, what are the dangers of
auto turning on 'ip cef' in the real world. Does it chew memory or process
power?
Any tips/ideas/observations would be gladly appreciated.
