Okay,
 
Well, It looks like the ip route-cache policy is only for fast switching. By default, CEF should be able to support PBR.
Here is a link:

Hi There

I am trying to configure PBR on an interface. This router is currently load balancing across multiple interfaces. Interfaces are running CEF. Now when CEF is enabled PBR does not work. Without CEF it works fine. Following is my topology and config

10.55.1.1 load balancing between multiple link --- -- R9 F0/0-------- ---- 192.168.20.0 -------- R10
=============
R9 config:

route-map pol per 10
match ip add 6
set ip next hop 192.168.10.1

access-list 6 per 192.168.20.0 0.0.0.255

Ip cef

int f0/0
ip add 192.168.20.1
ip load-sharing per-packet
ip policy route-map pol

=====================

traceroute from R10 when Cef is enabled (not working)

traceroute 10:55.1.1

1 192.168.20.1 8 msec 8 msec 8 msec
  2 192.168.21.3 4 msec
    192.168.24.9 20 msec
    192.168.21.3 4 msec
  3 .10.50.7.1 20 msec

traceroute from R10 when CEF is disabled on R9 int( no ip route-cache CEF) - working

1 192.168.20.1 8 msec 8 msec 8 msec
    2 192.168.10.1 20 msec
      3 .10.50.7.1 5 msec

==================

Any idea how to achieve this with out disabling cef

Thanks in advance
