3. Configure the router’s name to be RouterA:
Router(config)#hostname RouterA
RouterA(config)#
(note:the name changes
immediately)
4. Configure the vty lines with a password “cisco.” These are the available Telnet
ports for use from the Internet or from other networking devices on your network.
Without a password no one will be able to telnet into the router.
RouterA(config)#line vty 0 4
RouterA(config-line)#password cisco
RouterA(config-line)#login
RouterA(config-line)#exit
5. Configure the console line so messages will not interrupt what you are typing and
so your session does not time out:
RouterA(config)#line con 0
RouterA(config-line)#logging synchronous
RouterA(config-line)#exec-timeout 0 0
RouterA(config-line)#exit
Feeling frisky? Change exec-timeout to 0 1. This will cause your router session
to time out every 1 second (it can take up to about 5 minutes to start though).
There are only two ways to fix it: router recovery or press the “down” arrow key
while you change the exec timeout to a higher number with your other hand at the
same time. Doing this generates a continuous interrupt request to the CPU and
the session, therefore, does not time out. Logging synchronous is a nice
command. When you are configuring a router sometimes messages will interrupt
your work. Without this command in your script when you are interrupted you
will have to remember exactly what you typed when you were interrupted. With
this command the router will “refresh” what you typed on the current line.
6. Configure the secret password “cisco” and the enable password “class.” These are
required to have telnet access into your router. If you do not want anyone to be
able to telnet into your router, then not setting a password is one way to do it.
RouterA(config)#enable secret cisco
RouterA(config)#enable password class
7. To see what you have done so far you can always look at the runningconfiguration
file:
RouterA(config)#exit (or use control+Z to get all the way out)
RouterA#sh ru (short for show run)
