Another question,
in CEF is the whole routing table held in a cache? If so what is the
diffrence between this and the routing table held in RAM? Is the cache
faster than the regular RAM in the router?
Thanks,
Steve

Just for the sake of clarity: "cache" in this context doesn't refer to a
faster-than-usual memory. The route cache is in the exact same RAM as the
routing table. For more details, see the documents Marko mentioned.

Hi
I have a C2600 router with 32 MB of memory connected to my backbone. This
router should share the bandwidth among three Cisco routers connected
through the LAN (Fast-Ethernet ports). For example, a 3 Mbps bandwidth
should be shared between these routers so the traffic going through each of

Couple of items:
CEF is a very low overhead process and, in terms of
CPU and memory, you should be fine. I am not as
certain that your intentions to use the MAC address of
the router as a filter point will work. Typically you
use an IP extended ACL for CAR. Also review how
routers filter outbound
