To configure EIGRP protocol using cisco packet tracer simulation tool.
Algorithm
Step 1: Start – All Programs – cisco packet tracer – cisco packet tracer 5.3.
Step 2: Add the network device such as PC, switch and router in work area.
Step 3: Connect PC to switch using Copper media Straight through Cable in Fast Ethernet port and use serial cable for router to router connection.
Step 4: Apply the IP address and proper subnet mask.
Step 5: Configure EIGRP Protocol use the following syntax
R1(config)#router eigrp 10
R1(config-router)#network network-Address
Step 6: After complete configuration send the packet (Add Simple PDU) one network to another network.
Step 7: Check the data flow to the network use real time mode (or) Simulation Mode.
Step 8: Now EIGRP protocol was working well. Check the dynamic route and protocol use the command.
R1#show ip route
R1#show ip protocol
