3.
Third way to connect to a Cisco Router is via Telnet.
You can use telnet to connect to any active interface on a router such as an
Ethernet or serial port.
BRINGING UP A ROUTER:
When you first bring up a Cisco
router, it will run a power on self test (POST). If is passes, it will then look
for and load the Cisco IOS from flash memory, if IOS file is present. After
that, the IOS loads and looks for a valid configuration i.e. the startup configurations
that are stored in the non volatile RAM or NVRAM. If the startup configuration
is not present in the NVRAM then the router will broadcast looking for a valid
one on a TFTP Host. If the broadcast fails it will then go into what is called
the setup mode.
