Fast Switching mode

Hello !

I read that, by default, the "Fast Switching" mode was activated.
This means that 'ip route-cache' is configured, isn't it ?

Nevertheless, on my Cisco 7200 (simulator), the 'show run' command informs me that the "Fast Switching" mode isn't activated by default (I see 'no ip route-cache' in the running config).

Is the "Fast Switching" mode only activated by default on "smaller" series like 800 or 1700 ?

Thanks.

The different switching modes are:

Process switching
Fast switching
CEF Cisco Express Forwarding

Probably the 7200 is using CEF as its a high end router but i'm only guessing.

I believe that is correct. You won't specifically see it in the configuration, but if you put in the no ip route-cache you will see that. There are a lot of Cisco defaults that don't show in the configuration.
