Configuration of router in cisco packet tracer

Routers: A router is a network device that forwards data packets  between computer network. Routers perform the traffic directing functions on the internet . Data sent through the internet, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork until it reaches its destination node.

How to configure a router in cisco packet tracer?

fig 1: router configuration.

• the figure has two routers (namely 1910). taken from the tool box.
• the HWC2t port is configured by double clicking on the router and dragging the module present on the right on the router. While the router is off
• 
• connect the router using DCE serial cable.
• now drag and drop switches and pcs
• connect switches and pcs using copper straight wires in the fast ethernet ports.
• provide pc with ip address and gateway to the pcs.
• add IP address to the pc by double clicking on the pc and going to IP configuration mode.
• 
  
  
  
  
• connect routers and switches using Gigabit port.
• Configuration of routers :
• enable  (enables the router.)
• >router # config t       (enters into configuration mod)
• (#config ) Interface gig 0/1    (enter into interfacing gig port 0/1).
• #(config-if)IP add 192.168.100.10 255.255.255.0 (assign ip address to the network )
• #(config -if) no shut (exit out from the config mode).
• similarly for all the routers.
• after this config the wire turn green. that means connection is verified.
• configuring the serial ports of the routers:
• #interface Serial0/1/0
  Router(config-if)#ip address 192.162.100.10 255.255.255.0
  Router(config-if)#ip address 192.162.100.10 255.255.255.0
  Router(config-if)#no ip address
  no shut.
• similarly for the other router.

The packets can be verified using the ping command in command prompt.
