Configuring EIGRP on a Network

 

 

 

To configure EIGRP on a network use the following command:

 

RO1>enable

RO1#configure terminal

RO1(config #router eigrp 100

RO1(config-router)#network 192.168.3.0

RO1(config-router)#network 172.16.1.0

RO1(config-router)#no auto-summary

RO1(config-router)#end

 

From the command above, we used the command router eigrp 100 to turn on the protocol, then we declare all directly connected network on router RO1. All other routers on the network must be configured the same way, each router must declare its directly connected network to be seen by other routers on the network, and most importantly, all routers on the same network running EIGRP must be configured with the same process number 100

 

 

 

 

 

 

You want to redistribute routes that were learned by the router into the EIGRP routing process.

using the redistribute command:

 

Redistributing Routes into EIGRP:

 

HQ#configure terminal

HQ(config)#ip route 192.168.2.0 255.255.255.0 172.16.1.5

HQ(config)#router eigrp 100

HQ(config-router)#redistribute static

HQ(config-router)#end

HQ#

 

 

Setting the properties of the routes that are redistributed from another routing protocol with the default-metric command:

 

HQ#configure terminal

HQ(config)#router eigrp 100

HQ(config-router)#redistribute rip

HQ(config-router)#default-metric 1000 100 250 100 1500

HQ(config-router)#end

 

Use the show ip protocols command to view your route redistribution.

 

 

Creating a Default Route in EIGRP

 

You want to propagate a default route within EIGRP.

 

Configuring EIGRP to propagate a default route is by simply redistributing a static route to 0.0.0.0/0,

 

Use the following commands;

 

HQ#configure terminal

HQ(config)#ip route 0.0.0.0 0.0.0.0 172.16.1.5

HQ(config)#access-list 7 permit 0.0.0.0

HQ(config)#router eigrp 100

HQ(config-router)#redistribute static

HQ(config-router)#distribute-list 7 out static

HQ(config-router)#end

Router1#

 

If you log on to other routers, you will see that EIGRP is forwarding this route, and that it is accepted as a candidate default route. Use the following command to view:

Router2#show ip route 0.0.0.0
