Two routers configurations have been erased from memory and restarted. The network administrator needs to gather interface and neighbor information using CDP. What is the initial requirement to make CDP work between the two routers?
Interfaces on local and neighbor device must be up and IP addressing must be configured.
The interfaces on the connecting devices must be in the up/up status.
Interface on local device must be up and the IP addressing must be configured.
Routers will start in setup mode with all the Interfaces in shutdown mode, so on both local and neighbor routers, the interfaces must be configured and brought up with the "no shutdown" command.
Enable the CDP protocol with the command _enable cdp.
CDP is enabled by default in any Cisco router or switch. To use CDP there is no need to enable the protocol, unless it is disabled manually. Cisco Discovery Protocol (CDP) is a Layer 2 Cisco proprietary protocol used to find a Cisco neighbor device and learn about the type of hardware, software version, and active interfaces. Since CDP is a layer 2 protocol, there is no need to configure IP addressing on an interface, to make CDP work. Once the interface line is up and the protocol line is up CDP can do its job. If an IP address is configured on the interface of a neighboring device, CDP can gather IP information of that device and display it in the local router.
