Are you mixing up "CEF" and "CEF load-sharing"?  Running routers with "no ip
cef" is generally about as much fun as being fed into the bacon slicer
feet-first.

FWIW, I much prefer MLPPP over CEF load-sharing too, where the MLPPP support
on a platform is solid.  But that's for the ease of provisioning /
management / monitoring and QoS sanity you get from having a single L3
interface rather than due to any brokenisms in CEF.

Regards,
Tim.
