In this article, I’ll explain the simple configuration of EIGRP protocol on Cisco routers. But before to this, we must have an idea about EIGRP protocol that What is EIGRP Protocol? How to use it? Where can we use this protocol? Friends if you want to earn all the information about EIGRP then please read the complete article. EIGRP stands for Enhanced Interior Gateway Routing Protocol. It is an advanced distanced – vector protocol that is used for automatic configuration and decision making for a network. It is a sole Proprietary protocol available on Cisco Router especially designed by Cisco Systems for the purpose of Proprietary on Routing protocol of Cisco routers.
Basic features of EIGRP protocol –
- It uses the SPF algorithm which means Shortest Path First, so it connects first to the nearest device.
- Establish a connection with the neighbour.
- It is an RTP that is Reliable Transport Protocol.
- It updates the routing table periodically.
- It sends each update to all EIGRP routers.
The Best Usage of EIGRP protocol?
The best use of EIGRP routing protocol is at the private networks because it provides the best services like scalability, speed, ease of management.
Let’s learn the configuration of EIGRP on the Cisco router. Please watch given lab very carefully.
Now follow my steps to configure EIGRP on Cisco Routers.
1. Assign an IP address to all Router interfaces and all Systems/PCs.
On Router0
R0(config)#interface FastEthernet0/0
Router(config-if)#ip address 1.0.0.1 255.0.0.0
Router(config-if)#no shutdown
Router(config-if)#exit
Router(config)#interface FastEthernet0/1
Router(config-if)#ip address 2.0.0.1 255.0.0.0
Router(config-if)#no shutdown
On Router 1
R1(config)#interface FastEthernet0/0
Router(config-if)#ip address 2.0.0.2 255.0.0.0
Router(config-if)#no shutdown
Router(config-if)#exit
Router(config)#interface FastEthernet0/1
Router(config-if)#ip address 3.0.0.1 255.0.0.0
Router(config-if)#no shutdown
On Router2
Give IP address to Interface Fa0/0 that is FastEthernet0/0
R2(config)#interface FastEthernet0/0
Router(config-if)#ip address 4.0.0.1 255.0.0.0
Router(config-if)#no shutdown
Router(config-if)#exit
Give IP address to Interface Fa0/1 that is FastEthernet0/1
Router(config)#interface FastEthernet0/1
Router(config-if)#ip address 3.0.0.2 255.0.0.0
Router(config-if)#no shutdown
On PC1
On PC2
2. Now Configure EIGRP Protocol in Configure Terminal Mode
On Router0
Give the network address known to the Router Interfaces.
Router(config)#router eigrp 1
Router(config-router)#net 1.0.0.0
Router(config-router)#net 2.0.0.0
On Router1
Give the network address known to the Router Interfaces.
Router(config)#router eigrp 1
Router(config-router)#net 3.0.0.0
Router(config-router)#net 2.0.0.0
On Router2
Give the network address known to the Router Interfaces.
Router(config)#router eigrp 1
Router(config-router)#net 3.0.0.0
Router(config-router)#net 4.0.0.0

3. Now Check the Routing Table of Routers
On Router0
Put this show ip command in Enable Mode to check the Eigrp Protocol Configuration.
Router#show ip route
Gateway of last resort is not set C 1.0.0.0/8 is directly connected, FastEthernet0/0 C 2.0.0.0/8 is directly connected, FastEthernet0/1 D 3.0.0.0/8 [90/30720] via 2.0.0.2, FastEthernet0/1 D 4.0.0.0/8 [90/33280] via 2.0.0.2, FastEthernet0/1
On Router1
Put this show ip command in Enable Mode to check the Eigrp Protocol Configuration.
Router#show ip route
Gateway of last resort is not set
D 1.0.0.0/8 [90/30720] via 2.0.0.1, 00:06:07, FastEthernet0/0
C 2.0.0.0/8 is directly connected, FastEthernet0/0
C 3.0.0.0/8 is directly connected, FastEthernet0/1
D 4.0.0.0/8 FastEthernet0/1
On Router2
Put this show ip command in Enable Mode to check the Eigrp Protocol Configuration.
Router#show ip route
Gateway of last resort is not set D 1.0.0.0/8 via 3.0.0.1, FastEthernet0/1 D 2.0.0.0/8 via 3.0.0.1,, FastEthernet0/1 C 3.0.0.0/8 is directly connected, FastEthernet0/1 C 4.0.0.0/8 is directly connected, FastEthernet0/0
