Cisco Router Basic Commands video tutoial - Configure FastEthernetinterface

In the section one of CCNA lab video tutorial 3, we will configure Router2 and Router0 for the FastEthernet interfaces. We will set the ip address of FastEthernet interface 0/0 of Router2 as 10.0.0.1 with subnet mask 255.0.0.0, then turn on the interface with command "no shutdown". We do the same on Router0, set the ip address of FastEthernet interface 0/0 as 10.0.0.2 with subnet mask 255.0.0.0, then turn it on. We finally ping the ip address 10.0.0.1 on Router0 in order to verify Routers' configuration.
