Load balancing in routers

If by "round-robin" you mean by destination only, then this is correct. However, if 
you strict per-packet load sharing regardless of flow, then CEF does have this 
capability, although the default behavior is the flow-based load sharing you describe.

However, IIRC, code stability issues have plagued this feature in many IOS 
releases; I recall Intermedia selling a "bonded T1" product that used this feature, and 
supporting it was...not pleasant.
