This tutorial explains how to configure EIGRP (Enhanced Interior Gateway Routing Protocol) Routing protocol step by step in detail. EIGRP is an advanced distance-vector routing protocol that is used on a computer network for automating routing decisions and configuration.. Learn how to enable and configure EIGRP routing in Cisco router with practical example in packet tracer.
To explain EIGRP Routing, I will use packet tracer network simulator software. You can use this too but you can use any network simulator software or can use a real Cisco switch to follow this guide.
There is no difference in output as long as your selected software contains the commands explained in this tutorial.
Either you can create the following lab given below in the figure by self , following the command and the guide or you can download the lab it self which link is given below.
Configure the IP
IP configuration for PC
To configure the IP on pc you can simple double click on the pc then go to Desktop>Ip configuration and then enter the IP and default gateway.
This way configure the IP and default gateway on PC3 also .
IP configuration for Routers
We need to configure IP address and other parameters on interfaces before we could actually use them for routing. Interface mode is used to assign IP address. Interface mode can be accessed from global configuration mode and for which we can use the following commands
Router>enable Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#
From global configuration mode we can enter in interface mode. From there we can configure the interface. Following commands will assign IP address on FastEthernet0/0.
now we are all set up to configure the IP on router so let configure on each router and also make the port up.
R1(config)#interface s0/0/0 R1(config-if)#ip address 10.0.0.1 255.0.0.0 R1(config-if)#no shutdown R1(config)#interface fa0/0 R1(config-if)#ip address 192.168.1.1 255.255.255.0 R1(config-if)#no shutdown
R1(config)#interface s0/0/0 R1(config-if)#ip address 10.0.0.2 255.0.0.0 R1(config-if)#no shutdown R1(config)#interface fa0/0 R1(config-if)#ip address 192.168.2.1 255.255.255.0 R1(config-if)#no shutdown
Note- Since Serial Cable’s are having 2 ends DCE and DTE and for the real environment you need to configure the Clock Rate and Bandwidth on DCE ends . for the packet tracer if you don’t then no issue but in real keep in mind that it is necessary. so to do so you can apply the command below on the DCE ends.
R1(config)#interface s0/0/0 R1(config-if)#clock rate 64000 R1(config-if)#bandwidth 64 R1(config-if)#no shutdown R1(config-if)#exit
EIGRP Routing Protocol Configuration
Configuration of eigrp protocol is much easier than you think. It requires only two steps to configure the eigrp routing.
- Enable eigrp routing protocol from global configuration mode.
- Tell eigrp routing protocol which networks you want to aadd
Let’s configure it in R1 ( In my case i’ll add all the network in eigrp routing while it is up to you which network you want to add to perform the eigrp routing)
R1(config)#router eigrp 1 R1(config-router)#network 10.0.0.0 R1(config-router)#network 192.168.1.0 R1(config-router)#exit
Note- Here in first command 1 is the AS ID which you can take from 1-65535 . Just keep in mind that AS number should be same on all the routers you are configuring the Eigrp.
R1(config)#router eigrp 1 R1(config-router)#network 10.0.0.0 R1(config-router)#network 192.168.2.0 R1(config-router)#exit
Verify the Eigrp Routing
To verify the Eigrp routing you can run the following command and the result be look something like this. if you are configuring the same as above otherwise it may differ.
now let’s verify each route via sending the packets via PING . and for this go to pc2 then open the command prompt and issue the ping command with network id.
so here you can see its pinging and the routing is 100% successful .
