Objective: Become familiar with the router’s host table. Host tables can be used to set names for commonly used IP addresses, which helps with troubleshooting.

　　Lab Equipment: Router 1 from the eRouters menu

　　1. Connect to Router 1, and set the host name to California.

　　Router>enable

　　Router#config t

　　Router(config)#hostname California

　　California(config)#

　　2. configure an IP address of 195.42.36.10 255.255.255.240 on the Ethernet 0 interface;be sure to enable the interface.

　　California(config)#interface ethernet 0

　　California(config-if)#ip address 195.42.36.10 255.255.255.240

　　California(config-if)#no shutdown

　　3. Connect to Router 2, and set the host name to Tampa.

　　Router>enable

　　Router#config t

　　Router(config)#hostname Tampa

　　Tampa(config)#

　　4. configure an IP address of 195.42.36.12 255.255.255.240 on the Ethernet 0 interface; be sure to enable the interface.

　　Tampa(config)#interface ethernet 0

　　Tampa(config-if)#ip address 195.42.36.12 255.255.255.240

　　Tampa(config-if)#no shutdown

　　Tampa(config-if)#exit

　　5. Exit interface mode. You do not want to have to type California’s Ethernet 0 IP address every time you try to ping it from Tampa, so set a host table entry for California using the IP address 195.42.36.10.

　　Tampa(config)#ip host California 195.42.36.10

　　Tampa(config#)exit

　　6. Now you should be able to ping California’s Ethernet 0 IP address from Tampa just by typing ping California.

　　Tampa#ping California

　　7. Use the show hosts command to verify that the entry is stored in the router’s host table.

　　Tampa#show hosts
