ip route-cache

Answered Question

Hi

For troubleshooting reason, i configured on the interface, no ip route-cache.

After troubleshooting i configured, ip route-cache.

With show run, the interface shows no ip route-cache cef. My question is, does no ip route-cache disable ip cef on the interface?

thanks

AFAIK, "IP route-cache" enables fast switching on the interfaces and the router does per-destination load-balancing. With " no ip route-cache" the router enables " per-packet " load balancing. No ip route cache disables IP CEF on the interface.

you have to use ip route-cache cef to reenable it on the interface I beleive.
