EIGRP – Equal Load Balancing
Secara default EIGRP akan menerapkan load balancing pada link yang equal
Buatlah topologi diatas dan lakukan konfigurasi berikut ini :
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 f0/1
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-if)#ex
R1(config)#router eigrp 1
R1(config-router)#net 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 f0/1
R2(config-if)#ip add 24.24.24.2 255.255.255.0
R2(config-if)#no shutdown
R2(config)#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 f0/0
R3(config-if)#ip add 13.13.13.3 255.255.255.0
R3(config-if)#no shutdown
R3(config)#int f0/1
R3(config-if)#ip add 34.34.34.3 255.255.255.0
R3(config-if)#no shutdown
R3(config)#int lo0
R3(config-if)#ip add
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 24.24.24.4 255.255.255.0
R4(config-if)#no shutdown
R4(config)#int f0/1
R4(config-if)#ip add 34.34.34.4 255.255.255.0
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
Selanjutnya cek routing tabelnya
R1
R1#sh ip route eigrp
34.0.0.0/24 is subnetted, 1 subnets
D 34.34.34.0 [90/30720] via 13.13.13.3, 00:00:13, FastEthernet0/1
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 13.13.13.3, 00:02:03, FastEthernet0/1
4.0.0.0/32 is subnetted, 1 subnets
D 4.4.4.4 [90/158720] via 13.13.13.3, 00:00:13, FastEthernet0/1
[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
Seperti yang terlihat diatas, 2 jalur digunakan secara bersamaan untuk menuju ke loopback0 R4 (Equal Cost Load Balancing) yakni via R2 (12.12.12.2) dan R3 (13.13.13.3)
R1
R1#sh ip route 4.4.4.4 255.255.255.255
