How is traffic handled by the ASR 9000v satellite device?

A.
Local traffic is switched locally, and routed traffic is forwarded to the upstream ASR 9000
Router.

B.
Local traffic is routed and switched locally. The configuration is done on the upstream ASR

9000 and pushed onto the satellite ASR 9000v. Only traffic leaving satellite device is forwarded
over uplinks.

C.
All traffic is forwarded to the upstream ASR 9000 and no processing is done locally.

D.
All traffic is forwarded to the upstream ASR 9000, but minimal mandatory local processing is
done by the satellite device.
