I'm been reading up a little bit on policy based routing. One thing i'm a little bit confused about is if PBR is fast-switched by default on 12.4? Can it ever be cef switched?
in release 12.0 PBR was fast switched and we used to add a command called ip route-cache policy.
the command is still there
now on multilayer switches PBR is CEF switched and they are able to write PBR next-hops in the TCAM tables.
on routers neflow PBR has been introduced and requires CEF or dCEF
>> NetFlow policy routing (NPR) integrates policy routing, which enables traffic engineering and traffic classification, with NetFlow services, which provide billing, capacity planning, and monitoring information on real-time traffic flows. IP policy routing now works with Cisco Express Forwarding (CEF), distributed CEF (dCEF), and NetFlow.
And actually there is less attention to the first command described above.
Hope to help
