All steps are completed from sub commands in the Global Configuration Mode. Save your configuration after each step.

1. Give your router a hostname.
Router(config)#hostname "name of router" for example lab_a

2. Setup your enable passwords
Lab_a(config)# enable password cisco
Lab_a(config)# enable secret class

3. Configure interfaces with IP addresses and SN Mask
Lab_a(config)#interface e0
Lab_a(config-if)#ip address XXX.XXX.XXX.XXX MMM.MMM.MMM.MMM
Lab_a(config-if)#no shutdown
(Remember S0 must have a clockrate=56000 before the no shutdown) (repeat this step for each interface in use.)

4. Configure routing protocol and directly connected networks.
Lab_A(config)#router rip
Lab_A(config-router)#network network address (repeat this step for each directly connected network.)

5. Create IP host tables.
Lab_A(config)#ip host router name XXX.XXX.XXX.XXX YYY.YYY.YYY.YYY ZZZ.ZZZ.ZZZ.ZZZ
enter each address for the router with out hitting the enter key. Repeat the above step for every router in the network)

6. Configure line interfaces with login and password (line con 0, line vty 0 4 and line aux 0)
Lab_A(config)#line con 0
Lab_A(config-line)#password cisco
Lab_A(config-line)#login
Lab_A(config-line)#line vty 0 4
Lab_A(config-line)#password cisco
Lab_A(config-line)#login
Lab_A(config)#line aux 0
Lab_A(config-line)#password cisco
Lab_A(config-line)#login
