Basic Configuration For a Router Port and Router Based Network in Cisco Packet Tracer
ROUTER BASIC CONFIGURATION
Cisco Router ports are by default disabled (down). When you configure a router you need to enable the port. You need to set an IP Address for each port on a Router. This IP Address is used as default gateway. To configure a Router follow the instructions below.
- Click on the Router. A popup window will be opened.
- Go to CLI tab in the popup window.
- Click in command box.
- Type “no” to configure manually.
- Press “Enter”.
- To enable the switch give give following command:
enable
- To enable configuration mode give following command:
configure terminal
- To access a specific port give following command (Router have no fastethernet port):
interface gigabitethernet <PORT NUMBER>
For example for first port (Router port number starts from 0):
interface gigabitethernet 0/0
- To enable the port give following command:
no shutdown
- To set an IP Address give following command:
ip address <IP ADDRESS> <SUBNET MASK>
For Example:
ip address 192.168.1.1 255.255.255.0
- To save the configuration give following command:
do write memory
- To exit the port give the following command
exit
- To exit the configuration mode give following command:
exit
- To exit enable mode give following command:
exit
You are all done!
ROUTER BASED NETWORK
To create a Network using Cisco Router first set an IP Address to all PC. All PC will be connected by two or more Switch. Two PC with a Switch will be with same Network ID but Two PC with different Switch will be with different Network ID.
Then, Complete basic Router Configuration. Router will be connected to Switches only (not with PC). Each port of a Router that is connected to a Switch will be assigned to an IP Address. This IP Address will be in same network with all the PC those are connected to relative Switch.
Now, For each PC go to IP Address option again. Fill the “default gateway” box with the IP Address of the Router port to that they are connected by there Switch.
Your Network is Complete! Now You can Transfer Packet!
