Stephen,
I'm wondering if I've got a) an IOS bug
Send me the configuration and a description of what you are trying to accomplish (ie. what packets you want to redirect where) and I'll tell you if it's broken.
or if b) I need to turn off some kind of route caching/cef that works at layer 3 altho I've disabled everything I could think of on the interface
You should *never* have to disable a switching path to make a feature work. If you do it's a bug and please open a TAC case on it so the problem is fixed. Cisco IOS switching paths are designed such that if you enable a feature that is not supported in a particular switching path then that packet is punted to the next switching path to be handled.

Hi, I'm trying to setup a platform that will send different types of packets over different routes, theres a good example of what I'm doing at http://www.cisco.com/warp/public/cc/pd/ibsw/ibdlsw/prodlit/dlsw5_rg.htm under 'Directing Traffic Flows with Policy Routing' Basically, it doesnt work, I'm on IOS 12.0(3) and not sure if its a bug or just me. I'm using policy routing and route-maps to identify certain types of traffic by tcp port number using extended access-lists and then change the next-hop. Whats happening is that it works okay until the above access-list makes a match, after that all packets to that IP address regardless of port number get sent via the modified next hop. I'm wondering if I've got a) an IOS bug or if b) I need to turn off some kind of route caching/cef that works at layer 3 altho I've disabled everything I could think of on the interface Any thoughts?
