So I've been doing some more reading and it seems like the entries in show ip cache could be due to packets that cannot be CEF swiched & are punted to the next switching level ( FastSwitching )
The router in question is a 2611 setup for NAT/PAT for my internal home network.
Would this be a possibility as to why I see some entries in my ip cache?
I'm thinking that because the incoming packets to the router will have the destination address of my routers outside interface, that this causes my router to punt the packets down to FastSwitching.
Is this why?
