Make sure you are logged on remotely first.
All of my routers are connected to a switch called vlan_switch or vs for short. By
assigning specific vlans I can create links to the routers.

In addition, I can use my terminal server as a frame relay switch. By turning frame-relay
switching and creating the appropriate frame-relay route statements, I can create a virtual
mesh network. Then All I have to do at the routers is turn off frame-relay inverse-arp and
configure the dlci’s manually. (see file term_server.txt)

You can even prep the routers for labs by preconfiguring them and saving the config as a
filename other than startup-config. I have a file named baseline and others named for
labs. When I want to wipe out a routers config and go back to a blank screen with a few
options (hostname, port speed, descriptions, alias’s, etc) I issue the command “copy
baseline startup-config” then I reload and the router is just the way I want it. The same
can be done to prep the routers to get them to a state without the student doing hours or
redundant work to get to the lesson at hand.
Access to s 24 hours student lab could be easily controlled by a radius server.
Please feel free to telnet into citi.getmyip.com (password is cisco) and snoop around. (R2
and R5 have an active frame connection ) If you have any question don’t hesitate to ask.
