[yes/no]: yesBuilding configuration.[OK]Use the enabled mode 'configure' command to modify this configuration.Press RETURN to get started!Now that FortWorth’s initial configuration is complete, we can connect the interfaces.Router Setup OutcomeBefore you turn on a router for the first time, you should have some idea of what you are going to do with it because it is going to ask you to go through an initial configuration dialog and build a skeletal configuration on the router.I call the configuration a skeletal configuration because of its bare bones nature.The System Configuration Dialog allows you to turn on interfaces, assign addresses, and assign some passwords; however, it does not allow you to customize IOS configuration things like routing protocols and filters.With the System Configuration Dialog, we can quickly put a configuration on a router to allow the interfaces to come up and IOS to start routing and/or bridging.From there, we can make modifications.Just remember that a little up-front design work never hurt anybody.Our planning allowed us to very quickly run through the initial configurations two routers, Dallas and FortWorth.The process you have just seen is generally what it will look like.Of course, your mileage may vary based on the router model, the IOS version, and the protocols you need.Connecting the InterfacesA router’s interface must be connected to a network so messages may be received and routed or bridged from one network to another.This connection is as simple as plugging one end of an appropriate cable into the router’s interface and then plugging the other end of the cable into the physical network equipment such as an Ethernet hub or a T1 CSU/DSU (Channel Service Unit/Digital Service Unit).In our internetwork, we are using Ethernet and serial interfaces.These should be connected to their respective networks.CompletionOur routers are now configured and operational.The routers’ interfaces are connected to their networks, and the networks are operational.We now have a working internetwork.
