Hi All,

Another silly question....

Can you have Netflow Accounting without using ip route-cache flow ?

Reason is as per my last e-mail about fast switching policy routing and
the answer I got back from Kyle was that you needed to enable 'ip
route-cache policy' on the interface that the policy was applied.

I tried on a Lab router and it accepted both but I don't quite
understand how things will work?

Essentially I want to ensure that Netflow and Policy works but fast
switches for traffic.

Taking the config below apply fast switched policy routing to certain
traffic matching list ADDRESSES and all other traffic fast flow
switched. Netflow accounting is to be used.

!
ip cef
!
interface Hssi1/0
 ip address 10.1.0.2 255.255.255.0
 ip route-cache policy
 ip route-cache flow
 ip policy route-map HSSI-Policy
!
route-map HSSI-Policy permit 10
 match ip address ADDRESSES
 set ip next-hop 10.2.1.2
!
ip flow-export version 5 origin-as
ip flow-export destination 10.3.1.3 2054
!
