Lab 13. EIGRP – Mindah Jalur
– Delay
Kondisi normal tentunya trafik dari router R1 menuju Loopback R3 adalah langsung menuju router R3 melalui interface G1/0 karena perhitungan bandwidth Gigabitethernetnya.
Nah bila diinginkan trafik melewati router R2 dulu maka parameter metric bisa
kita rubah agar memenuhi hal tersebut, salah satunya adalah Delay. Kondisi
awal…

Tracing the route to 3.3.3.3
Kita bisa melakukan pengecekan pada EIGRP topologinya
untuk memastikan ada berapa jalur menuju ke 3.3.3.3.
IP-EIGRP (AS 10): Topology entry for 3.3.3.3/32
State is Passive, Query origin flag is 1, 1 Successor(s), FD is 130816
Routing Descriptor Blocks:
13.13.13.3 (GigabitEthernet1/0), from 13.13.13.3, Send flag is 0x0
Composite metric is (130816/128256), Route is Internal
Vector metric:
Minimum bandwidth is 1000000 Kbit
Total delay is 5010 microseconds
Reliability is 255/255
Load is 1/255
Minimum MTU is 1500
Hop count is 1
12.12.12.2 (FastEthernet0/0), from 12.12.12.2, Send flag is 0x0
Composite metric is (156416/130816), Route is Internal
Vector metric:
Minimum bandwidth is 100000 Kbit
Total delay is 5110 microseconds
Reliability is 255/255
Load is 1/255
Minimum MTU is 1500
Terlihat
diatas bahwasanya bandwidth G1/0 (1000000) lebih cepat dibanding pada fastethernet (100000) sedangkan nilai delay
Gigabitethenet (5010) juga lebih kecil dibanding delay Fastethernet (5110) Untuk
merubah jalurnya, kita memanipulasi nilai metricnya dengan merubah delay.
R1(config)#interface
g1/0
R1(config-if)#delay 1000000
Selanjutnya kita cek kembali EIGRP Topologi nya.
IP-EIGRP (AS 10): Topology entry for 3.3.3.3/32
State is Passive, Query origin flag is 1, 1 Successor(s), FD is 156416
Routing Descriptor Blocks:
12.12.12.2 (FastEthernet0/0), from 12.12.12.2, Send flag is 0x0
Composite metric is (156416/130816), Route is Internal
Vector metric:
Minimum bandwidth is 100000 Kbit
Total delay is 5110 microseconds
Reliability is 255/255
Load is 1/255
Minimum MTU is 1500
Hop count is 2
13.13.13.3 (GigabitEthernet1/0), from 13.13.13.3, Send flag is 0x0
Composite metric is (256130560/128256), Route is Internal
Vector metric:
Minimum bandwidth is 1000000 Kbit
Total delay is 10005000 microseconds
Reliability is 255/255
Load is 1/255
Minimum MTU is 1500
Terlihat diatas bahwasanya delaynya menjadi
semakin besar. Sekarang kita cek apakah routenya sudah berpindah melalui
Fastethernet atau tidak

Seperti yang kita coba traceroute jalurnya sudah pindah
jalurnya lewat R2 dulu baru ke R3.
