Switching Tech, Lab 20. HSRP - Track Route
Untuk topology masih sama, Konfigurasikan di R2
R2:
R2(config)#track 1 ip route 8.8.8.8/32 reachability
R2(config-track)#
R2(config-track)#interface FastEthernet0/1
R2(config-if)#standby 1 track 1 decrement 20
Verifikasi
Pastikan R2 memiliki route 8.8.8.8/32
R2:
R2#show ip route eigrp
8.0.0.0/32 is subnetted, 1 subnets
D 8.8.8.8 [90/158720] via 192.168.12.1, 00:06:05, FastEthernet0/1
13.0.0.0/24 is subnetted, 1 subnets
D 13.13.13.0 [90/30720] via 192.168.12.1, 00:00:44, FastEthernet0/1
R2:
R2(config)#do show standby brief
P indicates configured to preempt.

Interface Grp Pri P State Active Standby Virtual IP
Fa0/1 1 110 P Active local 192.168.12.1 192.168.12.254
R2 statusnya adalah active dan prioritasnya adalah 110, kemudian Shutdown interface loopback R3, dan perhatikan proses yang terjadi berikutnya.
R3:
R3(config)#interface lo0
R3(config-if)#shutdown
R3(config-if)#exit
Perhatikan statusnya akan berubah menjadi standby dengan nilai priority 90.
R2:
R2(config)#

Fa0/1 1 90 P Standby 192.168.12.1 local 192.168.12.254
Dari sisi R1 akan berubah menjadi active dengan priority 100
R1:
R1#show standby brief
P indicates configured to preempt.

Aktifkan kembali interface loopback R3
R3:
R3(config)#int lo0
R3(config-if)#no shutdown
R3(config-if)#exit
