Indeed. For example, policy-based routing (e.g. source address dependent
routing) has been claimed to be in the CEF path now (previously it was in
the slow path), but I certainly would "like" to be shown wrong. :-)
By low-end edge devices I basically meant all DSL, ISDN, cablemodem etc.
equipment. I don't know of "midrange" Cisco gear, but basically
everything service providers use (at least 7xxx, 10xxx, and 12xxx series)
do support CEF (or more complicated variations of it).
