Hello everybody ! I use a Catalyst 3550 for routing and switching my clients to the Internet. I established a BGP session with an ISP which give me a default route for Global Access and full routing table (BGP) for Metro Access. At the moment everything is going fine, but the memory resources are low. My question is : Is it possible to disable CEF on the switch port that is connected to the ISP ? And in this way the switch doesn't build a switching table with the bgp routes that it receives ? I receive from the ISP about 10k of metro routes and the installed memory on the switch is 64/8 MB.

Juergen, I know that everybody's advice is to use CEF, and this would be the best, if possible. In some cases, you have to deal with the hardware that you have and I just answer to the original question, how and if CEF can be disabled on Cisco 3550.
