Now that you have a starting point, you can follow up with some reading on
CEF and what is is and is supposed to do.
Sometimes the folks over on
What does the "no ip route-cache cef" does? Anyone knows? Thanks.

You might want to disable CEF-caching if you suspect you are having CEF
problems. CEF used to be (and sometimes still is) rather buggy.
That thing about how disabling CEF-caching also disables fast-switch caching
is a bug, I think. I have noticed that behavior myself sometimes, but I
don't thin
According to Cisco, no ip route-cache cef actually turns cef switching off
on that interface, if cef is enabled globally. If you are trying to enable
cef then you shouldn't use this command on the interface. Try these links,
below them is an example from a production router using cef per p
Hello,
When configuring cef for per packet for dual T-1 links to one isp, what do
the commands, no ip route-cache cef actually do?
Also, when I configure this command, it overwrites the no ip route-cache
command on that particular interface so I have to first type the no ip
route-cache cef
That is true and it's always enabled by default. Check the bugs for
fast switching 'cos it has quite a few issues with NAT, ISDN, Frame
Relay (sub-i/f), ISL on Fast Ethernet (sub-if again) and some other
stuff too.

if I am not wrong ip route-cache enable fast-switching while no ip
route-cache disables fast-switching and drops to process switching
so that's really a matter of enabling switching types between interfaces
hope this helps

Why what? :)
'ip mroute-cache' does the same things as 'ip route-cache' except for
packets with multi-cast destination addresses - if forces the router to
process switch them. Again, I think ths is mostly used for packet-by-packet
load sharing.

It determines how the router switches packets.
If you use 'ip route-cache' then the router will be fast-switching the
packets. The router keeps a cached memory full of recently used (which
should often equal heavily used) routes & destinations. When a packet comes
in it can
Can someone describe why I would want to use the ip route-cache (or no ip
route-cache) command. I've found references on the Cisco site about how to
use it, but not why.
