Today’s post takes us from a cleanly wiped router config (except hostnames), to one router being ready for Telnet support. As usual, you can do the lab on paper or in a text editor in just a few minutes.

Problem: Configuring Telnet

Cisco routers come ready to run Telnet. That is, there is very little you need to configure to make the router allow inbound Telnet connections. The trick for today’s exercise is to decide just what that bare minimum of non-default commands happens to be.

For today’s lab, configure only router R1 in the figure below. The initial config has all default configuration, except it already has a hostname R1 command, just so it is obvious which router is which. Your job is to list the configuration on R1 such that:

  1. A user at PC1, in the same VLAN as R1’s F0/0 interface, can Telnet successfully into R1
  2. The user has to supply only a password; no username is required.
  3. Configure no unnecessary commands (use defaults)
  4. Assume PC1, as well as all LAN devices, have already been configured correctly
