EIGRP - ROUTING #3

 

EIGRP - ROUTING

Alat dan Bahan :

  • Laptop / PC
  • Cisco Packet Tracer
          Routing Dynamic : sebuah routingan yang di buat secara otomatis pada sebuah table routing tersebut berdasarkan lintas jaringan ataupun router yang terhubung, biasanya table routing akan terisi otomatis saat kita menambahkan sebuah IP Address dan sebuah interface (gateway).

    Routing Dynamic EIGRP singkatan dari Enhanced Interior Geteway Protocol, merupakan protocol routing yang hanya dimiliki oleh Cisco system, only from Cisco Propitary.

    Karakteristik Routing EIGRP :

- Administrative Distance : 90
- IP Multicast : 224.0.0.10
- Hop count : 255
- ASN (Autonomous System Number) for Indentification Router Neighboor
- Hello Packet broadcast every : 5 Second
- Support Equal & Unequal cost load balancing


Perhatikan Topologi berikut : 


    Pertama yang harus dilakukan adalah konfigurasi pada IP Address pada setiap router :

KONFIGURASI IP ADDRESS :

Pada Router 0
Gateway to R-1:

Router(config)#int fa 0/0 --> Enable Interface

Router(config-if)#ip address 10.10.10.1 255.255.255.0 --> IP Gateway

Router(config-if)#no shutdown


Client

Router(config)#int fa 0/1 --> Enable Interface

Router(config-if)#ip address 192.168.10.1 255.255.255.0 --> IP Client

Router(config-if)#no shutdown



Pada Router 1 : 
Gateway to R-0 :

Router(config)#int fa 0/0 --> Enable Interface

Router(config-if)#ip address 10.10.10.2 255.255.255.0 --> IP Gateway to R-0

Router(config-if)#no shutdown


Gateway to R-2 :

Router(config)#int fa 0/1 --> Enable Interface

Router(config-if)#ip address 20.20.20.1 255.255.255.0 --> IP Gateway to R-2

Router(config-if)#no shutdown


Client :

Router(config)#int fa 1/0 --> Enable Interface

Router(config-if)#ip address 192.168.20.1 255.255.255.0 --> IP Client

Router(config-if)#no shutdown



Pada Router 2 : 

Gateway to R-2 :

Router(config)#int fa 0/1 --> Enable Interface

Router(config-if)#ip address 20.20.20.2 255.255.255.0 --> IP Gateway to R-1

Router(config-if)#no shutdown


Client :

Router(config)#int fa 1/0 --> Enable Interface

Router(config-if)#ip address 192.168.30.1 255.255.255.0 --> IP Client

Router(config-if)#no shutdown



    Kemudian dilanjutkan untuk membuat konfigurasi routing EIGRP pada setiap router :

Pada Router 0 : 

Router(config)#route eigrp 5 --> Enable EIGRP (ASN Number harus sama setiap router)

Router(config-router)#network 10.10.10.0 --> Network to Gateway

Router(config-router)#network 192.168.10.0 --> Network to Client

Router(config-router)#no auto-summary



Pada Router 1 : 

Router(config)#route eigrp 5 --> Enable EIGRP (ASN Number harus sama setiap router)

Router(config-router)#network 10.10.10.0 --> Network to Gateway

Router(config-router)#network 20.20.20.0 --> Network to Gateway

Router(config-router)#network 192.168.20.0 --> Network to Client

Router(config-router)#no auto-summary



Pada Router 2 : 

Router(config)#route eigrp 5 --> Enable EIGRP (ASN Number harus sama setiap router)

Router(config-router)#network 20.20.20.0 --> Network to Gateway

Router(config-router)#network 192.168.30.0 --> Network to Client

Router(config-router)#no auto-summary


    Konfigurasi pada routing dynamic EIGRP pada tiap router sudah selesai, sekarang untuk melihat router tersebut connect pada routing dynamic EIGRP dengan cara mengecheck pada routing table nya ;


CHECK ROUTING TABLE :


Router(config)#do show 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     10.10.10.0/24 is directly connected, FastEthernet0/0

L      10.10.10.1/32 is directly connected, FastEthernet0/0

        20.0.0.0/24 is subnetted, 1 subnets

D     20.20.20.0/24 [90/30720] via 10.10.10.2, 00:01:40, FastEthernet0/0

        192.168.10.0/24 is variably subnetted, 2 subnets, 2 masks

C     192.168.10.0/24 is directly connected, FastEthernet0/1

L      192.168.10.1/32 is directly connected, FastEthernet0/1

D     192.168.20.0/24 [90/30720] via 10.10.10.2, 00:01:21, FastEthernet0/0

D     192.168.30.0/24 [90/33280] via 10.10.10.2, 00:00:33, FastEthernet0/0
