I am learning about CDP (working on CCNA still), and I thought I understood it well enough.. then I read (Sybex CCNA 5th) that you can only get the IP address of directly connected devices.. does that imply that you can get other info from remote devices with CDP? In my home lab, I can't seem to, and at work where we have at least 12 routers and several switches, we only get neighbor info also... So how, if at all, can you get info of devices that are not directly connected (not including devices connected through an off-brand switch).
Thank you!
