Hi,


On an ISR G2 platform I can simply enter ip cef and be done.


On the ASR100o platfrom there is no default and must determine which of these below is appropriate.


Which would be the "equivalent" of what is being done on an ISR G2 platform?


router(config)#ip cef ?

  accounting          Enable CEF accounting

  distributed         Distributed Cisco Express Forwarding

  load-sharing        Load sharing

  optimize            Optimizations

  traffic-statistics  Enable collection of traffic statistics

Icaruso,


The ASR I'm sure has a hell of a lot more capabilities than the ISR G2 series.


ip cef distributed - This can offload your CEF onto a separate SPA card

ip cef load-sharing - Allows you to change load-balancing option suchas per packet load balancing etc etc.

ip cef accounting - Allows accounting services to be used for CEF


The other two I honestly don't know.


I hope that helped a little bit.
