Verifying Your Cisco Router Configuration Using Ping, Trace Route and Telnet

Obviously, the show running-config would be the best way to verify your configuration, and the show startup-config would be the best However, once you take a look at the running-config, and it appears that everything is in order, you can verify your configuration with utilities, like Ping and Telnet.

 Ping

You can ping with different protocols, and you can see this by typing ping

? at the router user-mode or privileged mode prompt.

Router#ping ?

 

 

you can easily  Ping destination address or hostname of your router to see the status of the router.

To find your destination address or a neighbor’s Network layer address, you either need to go to the router or switch, or you can type the following command from the global configuration mode : Router#show cdp nei  this will show all the  detail to get to the Network layer addresses, which you can use to ping the interface you or the services you want to.

Trace

Another useful utility is the trace program,  to find the path a packet takes as it traverses an internetwork. you can also use  Trace command  alongside other multiple protocols to verify your router configuration status.

From the global configuration mode: type: the following command.

Router#trace ?

This will  Trace route to destination address or hostname on your network.

Telnet

I think that Telnet is the best tool, since it uses IP at the Network layer and TCP at the Transport layer to create a session with a remote host. If you can telnet into a device, your IP connectivity must be good. You can only telnet for IP addresses resolution or verification, and you can use Windows hosts or router prompts to telnet from or into.

Router#telnet ?

WORD IP address or hostname of a remote system

From the router prompt, you do not need to type the command telnet. If you just type a hostname or IP address, it will assume you want to telnet.
