You can find images of the Cisco 1700 router on Techgenie, Cisco, Hypersurf, eBay or about any retailers which sells electronic computer devices. It shouldn't be hard to find at all.
CDP-(Cisco Discovery Protocol)
CDP Cisco Discovery protocol identifies the IP addresss of neighbor router in a corporate network.
whenever you log into your cisco router....

PPP with PAP
First you must decide what specific protocol you want to use. Then you configure it on the individual routers. Example, with Cisco routers: Router(config)#router rip Router(config-router)#network 10.0.0.0. Router(config-router)#exit Additional commands may be required for optimization. Note: I use RIP for illustration purposes, but it is usually not the best option for routing.First you must decide what specific protocol you want to use.

There are three major parts of the router that can be upgraded:DRAM memory, Flash Memory, and the IOS operating system that runs on it.DRAM and Flash can each be a maximum of 16 MB (try ebaying for cisco 2500 flash or memory), and IOS images can be downloaded from Cisco if you have a valid Cisco service contract.
Some recommended books about Cisco routers are: Cisco Router Configuration, Cisco Routers For The Desperate, Cisco Routers for IP Router, Cisco CCNA Routing and Switching.
Ports on Cisco routers can be enabled or disabled by the router OS. "Administratively Up" simply means that the port has been enabled by the router's OS. If a port is enabled (Administratively Up) and the protocol is down, then there is a problem with communications over that port. Problems could one of many including; bad cable on the port, the far end device is down, the protocol configurations on the two connected device ports are not configured correctly to enable communications.
