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.
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 ?
WORD Ping destination address or hostname
appletalk Appletalk echo
decnet DECnet echo
ip IP echo
ipx Novell/IPX echo
srb srb echo
To find a neighbor’s Network layer address, you either need to go to the
router or switch, or you can type show cdp nei detail to get the Network
layer addresses, which you can use to ping with.
You can also use the trace program to find the path a packet takes as it
traverses an internetwork. Trace can also be used with multiple protocols.
Router#trace ?
WORD Trace route to destination address or
hostname
appletalk AppleTalk Trace
clns ISO CLNS Trace
ip IP Trace
oldvines Vines Trace (Cisco)
vines Vines Trace (Banyan)

Router#telnet ?
WORD IP address or hostname of a remote system
