I think I'm just getting more confused and I'm sure someone out there knows the definitive answer.
In the URL you sent Michael, it says what I had always thought, the same-interface command enables fast switching on the same "IP" interface, i.e. logical interface. Then I went looking and found this URL: http://www.cisco.com/warp/public/105/44.html#Q1 which seems to back up Michael's point. If this were correct then why are you able to turn on/off route-cache on individual p-p subinterfaces? ??? Dave "Lomker, Michael" wrote: > > > interface.
