Lab 15. Eigrp – Equal Load Balancing

Pada dasarnya, eigrp menerapkan metode load balancing di link yang equal. Disini, dari R1 menuju R4 menggunakan 2 jalur dan semuanya adalah FastEthernet.

*R1

  •  R1(config)#int f0/0
  •  R1(config-if)#ip add 12.12.12.1 255.255.255.0
  •  R1(config-if)#no shutdown
  •  R1(config)#int f1/0
  •  R1(config-if)#ip add 13.13.13.1 255.255.255.0
  •  R1(config-if)#no shutdown
  •  R1(config)#int lo0
  •  R1(config-if)#ip add 1.1.1.1 255.255.255.255
  •  R1(config)#router eigrp 1
  •  R1(config-router)#network 0.0.0.0  
  • R1(config-router)#no auto-summary

 *R2

  •  R2(config)#int f0/0
  •  R2(config-if)#ip add 12.12.12.2 255.255.255.0
  •  R2(config-if)#no shutdown
  •  R2(config)#int f1/0
  •  R2(config-if)#ip add 24.24.24.1 255.255.255.0
  •  R2(config-if)#no shutdown
  •  R2(config-if)#int lo0
  •  R2(config-if)#ip add 2.2.2.2 255.255.255.255
  •  R2(config)#router eigrp 1
  •  R2(config-router)#network 0.0.0.0  
  • R2(config-router)#no auto-summary

*R3

  •  R3(config)#int f1/0
  •  R3(config-if)#ip add 13.13.13.2 255.255.255.0
  •  R3(config-if)#no shutdown
  •  R3(config)#int f0/0
  •  R3(config-if)#ip add 34.34.34.1 255.255.255.0
  •  R3(config-if)#no shutdown
  •  R3(config)#int lo0
  •  R3(config-if)#ip add 3.3.3.3 255.255.255.255
  •  R3(config)#router eigrp 1
  •  R3(config-router)#network 0.0.0.0  
  • R3(config-router)#no auto-summary

*R4

  •  R4(config)#int f0/0
  •  R4(config-if)#ip add 24.24.24.2 255.255.255.0
  •  R4(config-if)#no shutdown
  •  R4(config)#int f1/0
  •  R4(config-if)#ip add 34.34.34.2 255.255.255.0
  •  R4(config-if)#no shutdown
  •  R4(config)#int lo0
  •  R4(config-if)#ip add 4.4.4.4 255.255.255.255
  •  R4(config)#router eigrp 1
  •  R4(config-router)#network 0.0.0.0  
  • R4(config-router)#no auto-summary

Cek table routing di R1

*R1

  •  R1 (config)#do sh ip route eigrp

  34.0.0.0/24 is subnetted, 1 subnets

 D 34.34.34.0 [90/30720] via 13.13.13.2, 00:00:13, FastEthernet1/0

  2.0.0.0/32 is subnetted, 1 subnets

 D 2.2.2.2 [90/156160] via 12.12.12.2, 00:32:08, FastEthernet0/0

  3.0.0.0/32 is subnetted, 1 subnets

 D 3.3.3.3 [90/156160] via 13.13.13.2, 00:02:03, FastEthernet1/0

  4.0.0.0/32 is subnetted, 1 subnets

 D 4.4.4.4 [90/158720] via 13.13.13.2, 00:00:13, FastEthernet1/0

  [90/158720] via 12.12.12.2, 00:00:13, FastEthernet0/0

  24.0.0.0/24 is subnetted, 1 subnets  

D 24.24.24.0 [90/30720] via 12.12.12.2, 00:00:21, FastEthernet0/0

Bisa kita lihat, 2 jalur dipakai secara bersamaan untuk menuju R4 yaitu melalui jalur R2 (12.12.12.2) dan R3 (13.13.13.2)
