The functions of a dynamic routing protocol are the same as a static routing protocol. If the destination is unreachable in from a point of routing then the other path can be created to reach the destination. To learn about EIGRP refer to EIGRP fundamentals.

Steps to Configure and Verify EIGRP in Cisco Packet Tracer :

Step 1: First, open the cisco packet tracer desktop and select the devices given below:

S.NODeviceModel NameQty.
1.pcpc4
2.switchPT-Switch2
3.routerPT-Router2

IP Addressing Table:

S.NODeviceIPv4 AddressSubnet MaskDefault Gateway
1.pc0192.168.0.2255.255.255.0192.168.0.1
2.pc1192.168.0.3255.255.255.0192.168.0.1
3.pc2172.168.0.2255.255.255.0172.168.0.1
4.pc3172.168.0.3255.255.255.0172.168.0.1
  • Then, create a network topology as shown below the image.
  • Use an Automatic connecting cable to connect the devices with others.

Step 2: Configure the PCs (hosts) with IPv4 address and Subnet Mask according to the IP addressing table given above.

  • To assign an IP address in PC1, click on PC1.
  • Then, go to desktop and then IP configuration and there you will IPv4 configuration.
  • Fill IPv4 address and subnet mask.

 

2. Assigning IP address using the ipconfig command.

  • We can also assign an IP address with the help of a command.
  • Go to the command terminal of the PC.
  • Then, type ipconfig <IPv4 address><subnet mask><default gateway>(if needed)
Example: ipconfig 192.168.0.3  255.255.255.0 192.168.0.1

 

  • Repeat the same procedure with other PCs to configure them thoroughly.

Step 3: Configure router with IP address and subnet mask.

IP Addressing Table Router:

S.NODeviceInterfaceIPv4 AddressSubnet Mask
1.router0FastEthernet0/0192.168.0.1255.255.255.0
Serial2/010.0.0.1255.0.0.0
2.router1FastEthernet0/0172.168.0.1255.255.0.0
Serial2/010.0.0.2255.0.0.0
  • To assign an IP address in router0, click on router0.
  • Then, go to config and then Interfaces.
  • Now,  configure the IP address in FastEthernet and serial ports according to IP addressing Table.
  • Add IPv4 address and subnet mask.

 

  • Repeat the same procedure with other routers to configure them thoroughly.

Step 4: After configuring all of the devices we need to configure EIGRP protocols to the routers.

  • First, click on router0 then Go to CLI.
  • Then type the commands and IP information given below.
CLI command : router eigrp 10
network <network id>

Protocols for router0

Router(config)#router eigrp 10
Router(config-router)#network 192.168.0.0
Router(config-router)#network 10.0.0.0

Protocols for router0

Router(config)#router eigrp 10
Router(config-router)#network 172.168.0.0
Router(config-router)#network 10.0.0.0

Step 5: Verifying the network by pinging the IP address of any PC. We will use the ping command to do so.

  • First, click on PC0 then Go to the command prompt
  • Then type ping <IP address of targeted node>
  • As we can see in the below image we are getting replies which means the connection is working very fine
Example: ping 172.168.0.2

 

  • A simulation of the experiment is given below we are sending PDU from  PC0 to PC2 and PC1 to PC3:
