HOW TO CONFIGURE EIGRP ON CISCO ROUTER USING PACKET TRACER SOFTWARE STEP BY STEP GUIDE

HOW TO CONFIGURE EIGRP ON CISCO ROUTER USING PACKET TRACER SOFTWARE

In this article we learn how to configure EIGRP and how to verify EIGRP after configuration on cisco router using packet tracer software.

Introduction of EIGRP

What is EIGRP

EIGRP is called advanced distance vector and it is classless protocol. It is a standard protocol and use for cisco and non cisco device, but initially it was cisco proprietary. It is included all features of igrp. It supports upto 255 hop count and by default it supports upto 100 hop count.

Administrative distance of EIGRP is 90.It does not uses broadcast address .It only uses multicast and unicast address.

By default EIGRP uses bandwidth and delay to calculate the metric calculation.

In the above diagram we learn the configuration of EIGRP on cisco router using packet tracer software.

Configuration of EIGRP on cisco router using packet tracer

We have to follow two commands to configure EIGRP on cisco router. To enabling the EIGRP we use “router eigrp <AS NO>” (AS is the autonomous system no which should be same ,if as no is different routers can not build eigrp neighbour relationship). Secondly router has to advertise their network to configure the EIGRP.

For router0

#router eigrp 1

#network 10.0.0.0

#network 172.16.0.0

For router1

#router eigrp 1

#network 172.16.0.0

#network 192.168.1.0

verify of EIGRP on cisco router using packet tracer

After configuration we need to verify the configuration whether it is configured successfully or not. To verify the the neighbour table on the router0 we execute the below command.

Router#show ip eigrp neighbors

IP-EIGRP neighbors for process 1

H Address Interface Hold Uptime SRTT RTO Q Seq

(sec) (ms) Cnt Num

0 172.16.0.2 Se0/0/0 13 00:00:42 40 1000 0 4

To verify the topology table from the router0 we execute the below command.

Router#sh ip eigrp topology

IP-EIGRP Topology Table for AS 1/ID(172.16.0.1)

Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply,

r - Reply status

P 10.0.0.0/8, 1 successors, FD is 5120

via Connected, GigabitEthernet0/0

P 172.16.0.0/16, 1 successors, FD is 2169856

via Connected, Serial0/0/0

P 192.168.1.0/24, 1 successors, FD is 2172416

via 172.16.0.2 (2172416/5120), Serial0/0/0

To verify the routing table from router0 we execute the below command

Router#sh ip route

Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP

D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP

i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area

* - candidate default, U - per-user static route, o - ODR

P - periodic downloaded static route

Gateway of last resort is not set

10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks

C 10.0.0.0/8 is directly connected, GigabitEthernet0/0

L 10.0.0.1/32 is directly connected, GigabitEthernet0/0

172.16.0.0/16 is variably subnetted, 2 subnets, 2 masks

C 172.16.0.0/16 is directly connected, Serial0/0/0

L 172.16.0.1/32 is directly connected, Serial0/0/0

D 192.168.1.0/24 [90/2172416] via 172.16.0.2, 00:04:12, Serial0/0/0
